I've done some testing with the X-window suggestions at: https://gitlab.denx.de/Xenomai/xenomai/wikis/Troubleshooting#the_latency_test_shows_high_latencies
My results on an Intel PC with Xenomai 3.0.7, Linux 4.9, Debian 9.7 with xfce4, worst-case latencies: - Using Intel driver: 39.8 us - Using fbdev, 34.8 us - Setting Option "NoAccel", both with Intel and fbdev driver: 22.6 us - No GUI: 6.3 us So setting "NoAccel" helps in my case, but I'm also looking forward to further improve it.
