Re: [squid-users] squid cpu usage ..high??

hi joe

well a guru is a guru and no doubting that
well yes joe i did compile squid with the enable time hack option
ive now compiled a new one without it
now my figures are like this
client_http.requests = 31.505258/sec
client_http.hits = 14.794440/sec
cpu_usage = 49.813500%
i just hv a feeling that even this is abit on the higher side
ive compiled 2.4S1 with async-io and ummm 35 threads....
do u think that this is abit high given the load of abt 40 req/sec ..
do i need to decrease the no of threads or totally give up async io ..

also i ve not been able to get sufficient information abt the LFUDA and
GFUDA replacment plocies and related performance..any pointers to that
??
