Hi.
For the last few days I have had troubles with my squid (3.0.24) - it
gets
a lot of cpu, and
response time is very long, about 4000 ms. I didn't see any information
in cache.log, so I tried to upgrade to latest stable release - it
doesn't change anything. I have read a lot about high cpu usage when
squid
rebuild disc cache, so I try change cache_dir type from ufs to aufs or
coss (./configure said about remove coss from squid 3.x), but the
problem
still exists.
What am I doing wrong? My squid has been working perfectly for two years
:(. Here's my config.log and squid.conf:
./configure --prefix=/usr/local/squid-3.1.8 --enable-useragent-log
--enable-referer-log --enable-default-err-language=Polish
--enable-err-languages=Polish --enable-linux-netfilter --enable-ssl

Replace those with:

cache_mem 1000 MB
cache_swap_low 80%
cache_swap_high 100%
cache_swap_high should be something less than 100% (99% may be better).
Squid will ONLY begin the aggressive space clearing when cache_swap_high
threshold is passed. So with 100% this may cause active connections to be
stopped while 20% of the cache is discarded.

Set this to "cache_store_log none".
Rest of squid.conf are acls. I have about 30 - 40 mbps of traffic. On
You have "http_access allow sloneczko" at the top of this config. so its
possible your other ACL are not working.
board
are core2duo 1.8 ghz 4 gb ram on intel chipset, 2x SATA on soft raid
(for
cache - md0).
by "soft raid" you mean *software* raid? That is a disk IO killer for
Squid.
Any ideas? When I run -k debug I can't do anything - load has increased,
