Dear Ladies and Gentlemen, I am writing to ask your suggestions on why Squid 2.2.STABLE3 performs very badly compared to 1.1.20 on the same FreeBSD 2.2.8-STABLE host. Here are the differences between the squid.conf and the default :- pericles# diff squid.conf squid.conf.default 346d345 < cache_mem 20 MB 416,417d414 < cache_dir /www/squid-2.2.STABLE3/cache1 1000 16 256 < cache_dir /www1/squid-2.2.STABLE3/cache2 1000 16 256 1032d1028 < http_access allow localhost This squid caches for an apache 1.2.5 proxy located on the same host.

The caches are on 2 x IBM 4.3GB SCSI disks. I have tried disabling the rfc1644 T/TCP extensions unsuccessfully. The performance is *subjectively* worse. The clinet sees an initial burst of date then nothing .. as if something is blocked. Your suggestions will be rceived very gratefully, Thank you, Yours sincerely.
