Manu, try to replicate your problem but cannot, it's fast in my system! Maybe I need more info about how you have inited the spi devices connected...
defragster, the speed trick will not work on RA8875, it has limits for SPI speed and in library I have to use a lot SPI speed changes for Read, write, circles, etc. The speedups noticed by manu are just code that goes faster but SPI it's below Teensy limits, actually datasheet set limit to 12Mhz but thanks Paul's SPI transactions and SPI speed modulations I'm currently set to 20Mhz.
