I had really high jitter when I run latency test with Debian Stretch. So I installed Wheezy with LinuxCNC 2.7.14 I'm running latency test right now with several instances of glxgears running and I get a max jitter of 70000 ns on servo thread and 79000 on base thread. But I've only been running it for 10 minutes or so. I plan to leave like that a couple of hours to see if there's something strange. The funny thing is, sometimes the board starts working ok and the problem starts when I stop the thread and try to start it again.
watchdog timeouts would be caused by millisecond delays, a few 100 usec should not be an issue at 1 KHz.
I dont think there is any point using halcmd for this, I would use a real LinuxCNC configuration and watch for error messages.
