Re: [squid-users] Slow connect times

Try disabling client side persistent connections. Please tell us if
you see any different (or no difference at all).

Also keep an eye on your access.log to see if you can identify what is
causing the delay. access.log contains a quite detailed trace of the
time it takes to load a page and where it is spent (even more so for
NTLM auth).
