LinuxCNC Benchmarking

In order to benchmark the current latency we can use some of the tools bundled with linuxcnc

Latency Test

The first method is to just run latency-test and make a note of the maximum jitter value

latency-test

Latency Histogram

One method is to run a latency histogram.
There's a couple of buttons here for launching glxgears and taking a screenshot.
Try opening around 5 x glxgears, then running the graph for a while.

latency-histogram --nobase --sbinsize 1000 --show
