Do I have to change my test?

I changed my test to 1 hour and removed the sleep statement.
Still no measurable difference for performance and no CRC Errors with
both kernels.

See other mail about my thoughts about performance and CRC.

Apparently the test is hard on the CPU, I have two pytest processes
listed in htop one with 80%CPU and one with 60% CPU, approx 30% ram
usage of 512MB. I have no clue how it reaches the CPU values, there
should be only one CPU on the pi0w.

Interesting :)

### 5.10.17+ on pi0w ###

I'll switch boards to a pi3b and test again with these settings.
