lousy perf of Squid-2.2.STABLE3 compared to 1.1.20 on FreeBSD 2.28

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

< cache_mem 20 MB

< 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.

There are no alarming messages in cache.log (Here they are

The FreeBSD system has 128 MB RAM, is a P166 and has 256 MB of swap.
 The caches are on 2 x IBM 4.3 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.
