howdy,
I've got a dual proc AMD64 (2gHz) FreeBSD 5.3R system running two squid
processes (to take advantage of both CPUs). Each process is doing
around 195 req/s, and the total bandwidth is ~40Mb/s (gig nic via bge
driver). Squid is being used exclusively as a reverse proxy, with all content being served out of memory (very little disk activity).
Top shows:
CPU states: 16.0% user, 0.0% nice, 42.7% system, 7.6% interrupt, 33.6% idle Mem: 898M Active, 569M Inact, 179M Wired, 214M Buf, 171M Free Swap: 4069M Total, 4069M Free
PID USERNAME PRI NICE SIZE RES STATE C TIME WCPU CPU COMMAND 14598 squid 108 0 463M 459M select 0 39.2H 59.96% 59.96% squid 14605 squid 105 0 421M 416M CPU0 1 38.4H 49.95% 49.95% squid
but the % system time can fluctuate up to 60 at times. My question is
if this is about the type of performance I could expect, or if people
have seen better. I was expecting to see much better performance,
seeing how everything is being served out of memory, but maybe I'm
asking too much? 400 reqs/s from RAM doesn't seem like much. Is this a FreeBSD issue (anybody else with similar experience)? A majority of the cpu time being spent in system would seem to indictate such. What is all the system load? How can i tell?
Any help/pointers/remarks appreciated
thanks, jeff
