Hi! Sorry about beeing unclear. I know that I switched the underlaying RT os.
The jessie box runs: Linux beaglebone 3.8.13-xenomai-r83 #1 Thu Jan 5 01:32:32 UTC 2017 armv7l GNU/Linux And on stretch: Linux beaglebone 4.19.37-bone-rt-r33 #1stretch <tg://search_hashtag?hashtag=1stretch> PREEMPT RT Wed Jun 5 11:22:07 UTC 2019 armv7l GNU/Linux I switched all driver/config stuff to use the preempt rt stuff. The jessie box is perfectly fine. The stretch based one is unusable. I am wondering how others use a stretch based image and if I am doing something wrong and there is a "magic" kernel version that is fast enough to be used. I did a simple benchmark opening a text engraving gcode file from fusion360. On the Jessie box it takes ~20s from clicking load to display. On the stretch base box takes around 4 minutes... Or could it have something to do with the fact that the stretch image runs from SD and the jessie from internal flash? Is there so much disk I/O involved?
