The Solarflare sysjitter utility measures the extent to which the system introduces
jitter and so impacts on the user‐level process. Sysjitter runs a thread on each
processor core and when the thread is de‐scheduled from the core it measures for
how long. Sysjitter produces summary statistics for each processor core. The
sysjitter utility can be downloaded from www.openonload.org
Sysjitter should be run on a system that is idle. When running on a system with
cpusets enabled ‐ run sysjitter as root.
