The maximum jitter of a device roughly describes how well real-time requirements can be met.. If a device has a maximum jitter of 100us, then it must be expected that an event is handled up to 100us too late.

Use:
sudo lshw
to show the installed hardware.

Note: The jitter measurements here describe jitter performance, which are possible with a tweaked system. Depending on the installed kernel and running software the jitter may be worse. Better performance is possible, if the system is tweaked better.

These benchmarks were made to test the hardware.
