I think Florian Schmidt's web site has the latest latency tester.
I think
that would be very useful. Exactly what kind of latencies
would this tool measure?
Same as the existing CLI tools - it would start an RT thread that polls
on the RTC, then tell the user to generate some load (switch windows,
do a find /, pingflood the default gateway, whatever), then report back
the maximum latency. How do these tools relate to the latency tracer in the
realtime kernel?
The tester is a userspace tool to measure low latency performance, the
latency tracer is an in-kernel mechanism to determine which part of the
kernel might be causing a latency problem.
