Request for help measuring power consumption of Energy-Efficient Ethernet (EEE)

I have a QNEthernet library branch that implements IEEE 802.3az, Energy-Efficient Ethernet (EEE). Would anyone who has appropriate power measurement equipment be willing to compare the power consumption of your real-world Ethernet apps using this feature vs. not using this feature? No modifications are required, other than to use the branch instead of master. Also, whatever hardware your Teensy is plugged into needs to support EEE. For example, I know the eero hardware supports it.

Appropriate networking apps include those that process or send a lot of traffic over a link that supports EEE.

If so, I can assist with:
1. Getting the branch
2. Helping with your Ethernet code
 
I can log the USB power with 10uA resolution with 5 measurements per second, but with no triggering or precise timing. Also could try with an oscilloscope and current probe with less resolution but timing.
 
I don’t need much timing info, only average power consumption over some length of time, given a program that does lots of network activity. I suppose there are two types of programs:
1. Some real world program that does lots of networking and that isn’t mine, to avoid any potential biases, and
2. A program I provide that does networking.

I can supply #2, but I was also hoping for some other real-world applications being measured. I suppose I should get a USB power meter for myself…

Anyways, I hope what I’m requesting makes sense.
 
@bicycleguy what sort of equipment do you have, the 5 measurements/second one? (Brand, model, etc.) Basically, I’m curious what “good equipment” I should get.
 
Sorry for taking so long to get back. I have a 121GW multimeter from EEVBlog. It's an awesome meter and a little pricey.

For the specific task you are looking at this video does a good job of explaining the issues. The 121GW does the same trick as the uCurrent gold in the video as its design was influenced by the same guy. I'd buy the Current Ranger.
