help
|
There are many types and causes of latency. LatencyTOP
|
focuses on the type of latency that causes skips in audio,
|
stutters in your desktop experience or that overloads your
|
server (while you have plenty of CPU power left).
|
|
LatencyTOP focuses on the cases where the applications want
|
to run and execute useful code, but there's some resource
|
that's not currently available (and the kernel then blocks
|
the process). This is done both on a system level and on a
|
per process level, so that you can see what's happening to
|
the system, and which process is suffering and/or causing
|
the delays.
