Hi all,
I've squid-2.6.STABLE22-1.el5 installed on an Intel Pentium D box on
RHEL5. There are two main problems with this setup:
1. When I restart squid, it takes an uncertain amount of time to come
up! ranging from a minute to unlimited (till I restart again).
2. Even when startup successfully, on some clients it stops responding
for a while and pressing F5 continously for some time opens the page and
sometimes open the page without images & in distorted form.
I have tried 3 different versions of squid to remove the doubt about a
particular build's problem. I've tried squid-3.0.STABLE16-1.el5,
squid-2.7.STABLE6-1.el5 and now squid-2.6.STABLE22-1.el5. But no luck! I
am using squid in conjunction with Shorewall and shorewall has been
working just fine since last 3 years on same system.
Any idea what might be going wrong?
Squid startup takes however long it requires to:
* allocate base memory
* load the config
* allocate any extra memory required by config
* start all the helper processes,
* load the cache index
Further, can anybody suggest best
suited distro to use for this purpose?
Not really. It comes down to resources and speed. Speed of hardware and
speed of Squid version startup code (the latter being sub-optimal in all
releases so far, 2.7 having the fastest to date).
Someone here suggested SUSE
Enterprise but I haven't given it a try though as yet. Squid.conf is below:

shutdown_lifetime 5 seconds
5 seconds may be too short to dump the entire cache index to disk
swap.state journal on shutdown. One thing to check for is when Squid
starts up how often does it complain that the cache is "DIRTY"?
That complaint indicates that the index journal is not available (or not
complete) and Squid is falling back to a very, very slow startup
process. It then reads every single cached file in your 30GB cache for
meta data to rebuild the swap.state journal from scratch.
