Hello Tom, I downloaded the cyclictest suite and ran it several times. The average latency is 3 microseconds. Running it via ssh the max was 45 or 48 until I logged from a wireless keyboard and the HDMI video. I started X and LXQT during that startup, the max went to 58.
I just started it again with the -h option to produce a histogram, now the max is 62 and the average is 4.
