While testing my new FreeBSD port on FreeBSD 8.2, I see the master process starting stealing cpu cycles after 1st client connect, so: PID JID USERNAME THR PRI NICE SIZE RES STATE C TIME WCPU COMMAND 39240 11 root 3 76 0 126M 49784K uwait 6 1:38 17.77% python2.7
This continues after the last client has disconnected until shutdown of the server.
Profiling with Run Snake Run (thanks to Andre for the excellent how to) shows: The master process spent 98% in _psutil_bsd.get_virtual_mem(). Seems to be an expensive function in FreeBSD. Turning off the call in accesslog resolves the problem.
Thanks very much for tracking this down. Would you consider submitting a patch to our Trac instance? Thanks, -glyph
