[squid-users] Slow connect times

I am running Squid 2.5-pre10, RH7.3, Samba 2.2.5 + Winbind, and as little
adjusting to squid.conf as I could to get things going. I have wb_ntlmauth &
wb_auth working for NT domain authentication.

I am trying (hard) to replace a MSProxy Server but am not getting comparable
performance with Squid. Squid will respond nicely sometimes, other times it
will stall and take 20+ seconds to load a page with the page then displaying in
its entirety almost instantly. If you get impatient during a stall and click a
link again, many times it will load almost instantly right after the second
click. I am testing the same sites at the same time with the MSProxy without
any issue. DNS response times are not great, but that should be equally slow
for both machines. I have ran tests without authenticating at all and get the
same results so that's not the issue either.

I only have a few users testing the Squid box so the load is light. The MSProxy
box is supporting several hundred users so it's fairly busy. Both machines have
identical hardware, P2-300/128meg ram.

I pasted in the config from cachemgr in hopes someone can point out to me where
I've missed the boat. I'm also curious why things commented out in the
squid.conf file still show to be active in the cachemgr dump.

Thanks for the help in advance. Tim Price
