If these numbers increase between > rt3 and rt4 then we have a hand full patches to look at. Usually signaltest generated reproducible results. I did see those higher numbers also for v5.10-rc1-rt1 (forgot to post those). For arm64 the max latency was even higher, around 450us. But I don't have a lot of data so I wouldn't jump to any conclusion. > just like that? Yes, Just fired up signaltest 5 times for arm64 and x86_64 with the latest release. Keep you posted.
