Package: hybserv
Version: 1.9.2-4.1
Severity: normal
Tags: upstream patch
HybServ uses select() to determine if any input is received. It has a timeout
so other stuff (e.g. timers) can happen in the mean time too. In src/sock.c the
timer is set with a timeout of 200µs. On my server, this amounts to around 5%
of continuous CPU usage while doing absolutely nothing. None of the timers run
more than once every second.
It looks like
http://hybserv2.svn.sourceforge.net/viewvc/hybserv2?view=revision&revision=1370
was supposed to lower the timeout from 1 second to 0.2 seconds, but it is now
in fact 0.0002 seconds (usec != msec).
