I would bet that an strace on the master pid would reveal that you
are calling poll, not epoll.
There are several postings on the list about applying the epoll
patch, but IIRC, you need to explicitly --disable-poll --disable-
select --enable-epoll for it to work.

Subject: squid performance epoll. 350req/sec 100% cpu
Hello.
I am tring to optimize squid for best possible performance.
it is in production and it's doing more than 350req/sec.
At peaks upto
500req/sec.
My problem is only one. 100% cpu. :-)
I tried to update my debian to 2.6.16 and recompiled squid:
Squid Cache: Version 2.5.STABLE12
configure options: --prefix=/usr --exec_prefix=/usr
--bindir=/usr/sbin
--sbindir=/usr/sbin --libexecdir=/usr/lib/squid
--sysconfdir=/etc/squid
--localstatedir=/var/spool/squid --datadir=/usr/share/squid
--enable-async-io --with-pthreads
--enable-storeio=ufs,aufs,diskd,null
--enable-linux-netfilter --enable-arp-acl
--enable-removal-policies=lru,heap
--enable-snmp --enable-delay-pools --enable-htcp --enable-epoll
--enable-cache-digests --enable-underscores --enable-referer-log
--enable-useragent-log --enable-auth=basic,digest,ntlm --enable-carp
--with-large-files i386-debian-linux
the thing I realy don't like is 25% cpu + 50% system cpu .
why the 50% system!!!!!
can anyone help?
Kind Regards
