For those of you who are able to try this, sounds like you just install linuxcnc-uspace and then run latency-test. Also install/try latencytop, although Linux CONFIG_LATENCYTOP is not enabled in Debian probably. $ apt-file search latency-test linuxcnc-uspace: /usr/bin/latency-test linuxcnc-uspace: /usr/share/doc/linuxcnc/examples/sample-configs/apps/latency/latency-test.demo linuxcnc-uspace: /usr/share/man/man1/latency-test.1.gz -- bye, pabs https://wiki.debian.org/PaulWise
