[H-GEN] Poor performance of squid-2.5 on Redhat 7.2 compared to Solaris 8 on x86

I would suggest clearing logs, put both squid into a high debug mode and
access a few URL's, just for about a minute and then compare the log files
to see if the Redhat version is performing extra steps that the other is
not.

Hi,
I've been working with squid for some time on low end x86/solaris platform.
I concocted a really slick config on that worked well to impress the powers
that be such that bought some new IBM PIII/1.13Ghz 512Mb etc etc to replace
the solaris X86 P200 128Mb etc... woopee! except they wanted Redhat because
IBM support redhat....

Anyway we have a url we can access that indicates download speed and for
some reason the solis box ALWAYS leaves the Redhat box for dead....1500Kbps
vs 200-300Kbps

The same speed applies for the bundled version of Squid in Redhat that is
2.4S1.

I recompiled the exact same versions on solaris as redhat with the same
options....
./configure --prefix=/opt/squid-2.5 '--enable-storeio=ufs diskd null' --
enable-icmp --enable-delay-pools --enable-useragent-log --enable-
referer-log --enable-snmp --enable-underscores '--enable-auth=basic ntlm' '-
-enable-basic-auth-helpers=PAM' --enable-ntlm-auth-helpers=NTLMSSP
except I included LDAP in the helpers on redhat
Squid is configured on both with a null cache_dir but otherwise is pretty
stock standard.
Solaris/Sqiuid still wins by a factor of 5!

Is there any trick to Squid on Redhat that I should know about? Can anyone
offer any advice on trouble shooting this?

Thanks in advance
Peter Arnold
