Teensyduino 1.56 Beta #1

... mister congenial here ...

Came back and TyComm was 'Not responding'.

Terminated and restarted. Changed its T_4.1 to .Av4Write each 100ms ... picked 100ms to shortcut the 120ms teensy timeout.
> started slower - showed a screen of garbage - picking up some speed ... another screen of garbage just seen.
> disabled TyComm save to RAM Disk.

Tsermon still running - with no .Av4Write
> with no while(.Av4Write) test it shows nothing under 50K lps, not seen any garbage pass, have seen it 'pause' and recover 2-3 times.

Tsermon and TyComm sharing some of same issues, except current Tsermon not showing garbage: suggesting indeed as expected the problem is in windows buffer handling, though the GUI may not display as fast as the data stream appears either.

Sort of interesting that Two nonstop T_4.1's working as well as one?

Of 16 (8*2) cores TWO are at 100%. One is 100% kernel time and the other about 30%. Those two are TyComm as 'Stop Serial' drops them out, except 15% of the shared core stays tied to Kernel.

One other core is ~60% with half Kernel time - assume that is Tsermon, and perhaps one more core at ~70% kernel time?

Other 12 cores all 3 to 13% showing Kernel time with some spikes.

TyComm just froze on garbage and went 'not reponding' ... so it is NOT keeping up as well as Tsermon ( and that it with possible waits each 100ms) - though it is monitoring 3 of 4 T_4.1 ports - where the two Dual Serial USB1 ports are idle - it is doing that on 1 thread AFAIk as implemented.
 
First: I agree that it is not a high priority issue.
Second: I always said that the speed test says not much for the speed of the Teensy. I think we all agree that not the Teensy is bottle neck.

Here is a summary of my constructive contributions ;)
---

More important than speed is that all the data gets transferd completely. Without missing lines. And, for Windows - perhaps with less garbage (If there is a way).

For the Windows issue, I already posted a demo which seems to be error-free. I don't say it's the best way to do make these kinds of tests - but it is the first one which does not show garbage, and without missing data.
I hope there there are better ways than to delay() a couple of seconds!

For the "missing data" issue I posted a version of usb_serial. It did some tests and it seems to work at least much better than the existing code. For me, on my system.
Maybe you can just try it?? I don't know if it is the "best" solution or if it works better on your systems. I only did some 100MByte tests.
I don't say that it fixes everything. It a very simple change, it just adds some memory barriers.
Yes, you tested them too - maybe my changes are a bit different, and I had more luck? Or, maybe it was just luck during my tests. Without trying more, we'll never know.

We probably should create a reliable test first. One, that lets us see quickly if the received data are correct. Maybe something with a checksum, and a short C code that takes the role of the terminal. My proposed way, the "log to file" works too, but it is cumbersome.
Without a test, we'll never know what we do. Watching scrolling lines is no good way, for sure.
At least we need to use tools that log to a file. Fast and reliable.

Edit: Still, on Windows, H-Term is the best I found. And with the Windows-test mentioned above, the screen-output looks good too. It shows a consistent, constant speed without fluctuations and the logged file is good.
The missing lines I mentioned earlier turned out to be the Teensy issue.

For the Arduino Part: I mentioned that it seems to help to increase the memory. On my system.


----
If you want to do rewrite that completely: I'd think that a !thread-safe! ringbuffer would be good. Doesn't c++ have a ready to use solution (for the buffer part?) ? (not sure if it thread-safe) It might have some overhead - but first, its more important to have reliable code here.

For Windows, yes, I agree. Windows is slow!

For Linux and MacOS, at least with Teensyduino serial monitor receiving and Teensy transmitting Serial.print(integer), CPU speed on Teensy does appear to be the bottleneck.

Can't do this right now, but I've saved a link to msg #108 on my list of issues to investigate so I won't forget.

At this moment I'm playing with MTP.
 
Taskman suggests all the code is limited by power of one core - and it is busy, especially TyComm at 100% trying to keep up. Though if interpreted right the one for Tsermon wasn't hitting 100% - so maybe the kernel part getting overwhelmed in handing off the data with a bottleneck somewhere. But overall running two T_4.1's at 600 MHz - both together ran the same as one alone. I got this Intel 10th Gen in Feb - just before the 11th Gen when USB got some upgrade, not sure if that would make a difference? It seems to where lesser power 11th gen i7 laptop seems as good or better on SSD's - though diff brands. Except the same unit on laptop that is good, was awful in the Desktop and I got it replaced.
 
@Frank - replaced the usb_serial.c code with that posted. I saw three pauses, perhaps some early garbage and for sure tons of garbage and a pause that lasted about 146 seconds. Below shows it still starts slow - then speeds up - the last two show the time between the start stop of garbage and pause seen here:

I wouldn't bet much on this - as long it skips data - you showed that yourself with your sceenshot (A screenshot with ~100 Lines skipped - it it's more likely thousands over the time). So, the printed lines/second is a random number, with zero meaning.

Yup - The code can't prevent garbage - it's a windows issue.
It also can't do anything against the pauses - it's a serial monitor issue. Obviusly a change of code on the teensy can't help against these PC Software issues.

But it should help a bit against missing lines.

If you can show an example where it still has missing lines - well, then my fix is not sufficiant.Can you show this? If yes, We'll have to dig deeper.

Well...

I could not resist.
Wrote a short program in C.
With my version of usb_serial.c:
Code: 
C:\c>serialtest COM3 
Port: COM3
After start, you'll probably see some garbage. Things will normalize after a few seconds.

Batchvorgang abbrechen (J/N)? Batchvorgang abbrechen (J/N)?

250MBit per second. Theoretical(!) max is 320Mbit/s
Edit: Switched to a dedicated USB with it's own controller. Now it hits 260MBit often.

10x times the speed of H-Term.

No! Garbage (hmmm why?? is the new tool fast enough that windows finds time to handle its memory correct in usb_ser.sys?)
No! missed lines.
No! pauses.

0.7...2.3% CPU on my Ryzon 5 2400G

Sometimes a few bytes missing - not sure what the reason is. But it's pretty OK now. Might be an additional, even more strange race in usb_serial.c.


With this code:
Code: 
//Use a Terminal that can log to a file.
//Check if the line numbers fit.
//Windows: There is a memory bug in the USB CDC driver, so you'll probably see strange results.

const int n = 100000;
volatile uint32_t t;

void setup() {
  Serial.begin(9600);
  //while (!Serial);
  delay(1000);
}

void loop() {
  t = micros();
  for (int i = 1; i < n + 1; i++) {
    Serial.print("123456789\n");
  }
  t = micros() - t;
  Serial.printf("%d Bytes in %d us = %0.2f Megabits per second\n", n * 10, t, (double)n * 10 * 8 / t);
  delay(10);
}
10ms delay only after a packet. No delay during packets, no availableForWrite().


Can upload my testcode somewhere - if Paul or Tim are interestet- But it works for windows only and does exactly this test only.
Pretty unusable for any other usage.
Executable attached. Give it some time after start so that things can normalize. Remember, it starts with having timouts on teensy (because there is no com-port open at this time) and probably filled buffers on the PC side.

Wonder what the linux speed would be....

Math for 225 Mb is 28 MB/sec and for 32 byte lines in lps test that would be :: 878k lines per second.

Paul reports 800 to over 1,000 lps typical for linux.

NOTE: That was with FrankB altered usb_serial.c. Reverting that showing SIMILAR results most under 229 Mbs, maybe some higher avg toward 245 Mb/sec?
 
No, Paul reports it for his version of usb_serial which does not wait and skips data. Apples and oranges.

Hm, it seems not to like "select copy"-
But you can just use this : serialtest COMx > output.txt (You can stop with CTRL+C)
This redirects the output to a file.

Not sure if that leads to garbage, too.... might be worth a try?
Windows seems to be pretty bitchy :)
 
Updated prior post - that was with edited usb_serial.c - reverted that and seems unchanged.

If you posted code for serialtest.exe that could be cool.

Indeed the unchecked output to SerMon isn't a good measure where any losses give a false result.

The Garbage from 'select copy' give a good idea of the problem though. It works fine with perfect attention to the incoming data, and gets confused/broken when there is a 'break' in the system.

Not sure what the 'output rate for the Windows GUI' is? How many 32 byte lines can stream in a window before the system 'slows' or blocks?
 
Film is over and it is 0:28 here.
Removed the delay() in the teensy sketch completely - still works.

Hitting 260MBit/s

Good night.
 
Removed delay() in sketch and saw one:
Code: 
Lines-Delta: 100000. Received: 1000000 Bytes in 36329 us = 220.21 Megabits per second
[U]Lines-Delta: 2165. Received[/U]: [B]123456123456789[/B]
Lines-Delta: 97731. Received: 1000000 Bytes in 36324 us = 220.24 Megabits per second

No garbage - but that broken string and that shows up after 'select and copy' too, or just clicking then resuming.

Was wondering if larger lines would be more efficient ... overwhelming
 
Tim, quite possible. Perhaps add a second param with the line length to the program?

Uploaded the code here : https://github.com/FrankBoesing/cdcbench
It just prints everything with line length != 10 and counts the lines between - pretty simple.

A CRC check is not used because, I think we just can trust the USB inbuilt CRC.

Well, now, what does that say?
My thoughts:

- Windows USB CDC is not slow. - The applications are slow. Because of the GUI? Don't know.
- When the app is fast enough, we see no garbage
- BUT: it's possible to influce it from the outside. Some action on the PC causes garbage from time to time, but very infrequent.
- After start, sometimes, it takes 10 seconds until everything is "burnt in" and the output becomes reliable. That's normal (Teensy USB is in timout state and PC buffer might be full right after start)
- There still seems to be a minor issue with usb_serial.c

@Frank: Hardcoded at 36 and 32 bytes and both were slower.

Some check beyond finding '\n' might catch minor buffer passing errors :

Bumped to 64 chars - no faster here - avg now ~215 not ~225.

Got this once early:
Code: 
Lines-Delta: 99920. Received: 6400000 Bytes in 241294 us = 212.19 Megabits per second
\;Lines-Delta: 0. Received: ╢═╔f▀Æ8∙♣ÅâPlLines-Delta: 87396. Received: 6400000 Bytes in 237785 us = 215.32 Megabits per second
Lines-Delta: 99936. Received: 6400000 Bytes in 228460 us = 224.11 Megabits per second

And a couple not hitting 100K copies - and 99984 is common. Seems like a full 1024B of buffer is dropping - 16 sets of 64B:
Code: 
Lines-Delta: 100000. Received: 6400000 Bytes in 260126 us = 196.83 Megabits per second
Lines-Delta: 99984. Received: 6400000 Bytes in 271170 us = 188.81 Megabits per second
Lines-Delta: 100000. Received: 6400000 Bytes in 271671 us = 188.46 Megabits per second

I count SIX only getting 99984. one at 99972 and one 99968. The x72 is odd set of 256, the others 512 multiples.

Two more x84's have gone by - so each lost two 512B buffers. And a x92 just went by.

I did add this to the 'c' code : if (lcnt != 64 || '1' != line[0]|| 'z' != line[30] ) {
testing this string: Serial.print("13579abcdefghijklmnopqrstuvwxyz_02468ABCDEFGHIJKLMNOPQRSTUVWXYZ\n");
> Is has not triggered as the printed line is always the expected 'Sketch Received' line[].

Did a Fork and PR.
Only print the detail every 50 lines when the transfer is 100,000 lines to make errors easier to see and count and it is usually this:
Code: 
Lines-Delta: [B][U]99984[/U][/B]. Received: 6400000 Bytes in 233203 us = 219.55 Megabits per second
.....

>> also when garbage comes it prints '_X's for each duplicate set of ZERO lines. When I enlisted in your GitHub the computer hit a WHOLE string of "ZERO" lines with garbage characters.

Tomorrow I'll add the optional DUAL SERIAL stats collection?

Virus scan just completed - caused this bad group of errors?

I wouldn't bet much on this - as long it skips data - you showed that yourself with your sceenshot

Yes, there is a data skipping problem on MacOS. While I have not yet come up with a good way to measure (and I plan to keep focusing most on MTP for the next week) every appearance is the vast majority of the lines are received on MacOS.

So far I've not see any data skipping happen with Linux. But again, this is just watching the ~30 Hz update rate of the serial monitor window and occasionally stopping auto-scroll and looking at the buffered lines.


So, the printed lines/second is a random number, with zero meaning.

Kinda don't agree with "zero meaning". But yes, if some percentage of the lines are skipped, the reported speed very well may be too optimistic by approx that amount.

I also believe there is some meaning to be observed by the relative stability of the numbers.
 
Indeed 'not zero' but compromised when lines go missing. That's why the storing stats on the output rates seemed cool with dual serial.
> observing them being stable would be meaningful ... they tend to be bouncy here on Windows ... again collected stats show that.

For some reason Frank's p#142 cdcbench as noted is dropping buffers in multiples of 512 bytes - and some rare 256B cases. That seems interesting?
> seems to run fine until the computer thingy multitasks? Though I can't trigger it just yet - seemed to happen getting the github fork, and again just before MalwareBytes popped up saying it was done a scan.
> the last 3000 sets of 100,000 prints of 64 bytes all came over without detected loss/error at ~210 M bits/sec to that cdcbench code.

Maybe, but you don't know this...

Also, I'm not sure what the topic here is.
Is it the different speed of different OS?
Or do we try to fix the problem?

Personally, I don't care which of the three OS is the fastest. It's very unimportant for me. It more interesting how to maximaize the througput while having no errors. Well, that's my opinion.
 
I've now caught up to reading this thread. These last couple days have been mostly MTP and a furniture move this weekend, so I'm behind on most forum stuff.

Frank B said:

Yes, agreed. I've really not put in a lot of work on this yet, really only just watching the lines in serial monitor and other programs (never did get hterm to work well...) Again, MTP and lingering minor issues holding up releasing the 1.07 bootloader are my top priority right now.

I see you posted a test program on msg #134. Will give it a try sometime within next week. Any chance you'll share the source? Or port it to Linux and MacOS?
 
The code is on Github.
Not sure if I can port it... can't do reliable tests with a VM I have this Windows machine only.
But its not the main intention to do speed tests. It's more written to find dropped USB packets - and this works on Windows too. I believe the Teensy drops them.
