Hi. I'm seeing periodic odd behavior from one of our squid2.6 stable18
(and stable22) boxes during the peak hours when the squid is busiest,
but not off-peak, and no other signs of a capacity limit except the
occasional queue congestion warning. About 15% of the requests
for one url we're

This may be the culpit. Squid-2 is very very poor at handling large
objects in memory,
Aside from the slight RAID5 performance drawback
and the RAID0 failure case drawbacks, I thought the
main performance issue with any RAID under squid
was with aufs only having a single writer thread,
as compared to giving squid multiple writer
threads if you mount the disks individually.

F5 has some documents on how to implement consisent hashes in bigip
irules (tcl),
but i wound up writing a custom one for use in front of our squids
that only does one
checksum per request, as opposed to one per squid in the pool, to avoid wasting
cpu cycles on the LB.
it uses a precomputed table
hi. this might belong on squid-dev, but figure i'll try here first.
squid doesn't know if an object is even cacheable until it gets
the headers back from origin, thus collapsed forwarding seems
to impair performance of non-cacheable content, by blocking
what will have to be a separate request
Aside from the fact that this one is an old version
(below), it's a little distressing to see squid occasionally
filling up a 1024M partition when configured for:
cache_dir aufs /mnt/squid 950 32 384
It's the only thing using the partition,
and sometimes squid clears it out itself
within a few

Hi. Our squid appears to be caching .css for only a few seconds,
when I expect it should be caching it longer, and doing IMS requests.
I've included log excerpts (MISS/HIT/MISS/HIT) and sniffer output below.
I've tried both of the following refresh_patterns with no noticeable change:

Squid deliver resources with expiration times in the past, thus causing

That was my assessment as well: no object eviction?!?
So if your dataset it small enough, then varnish could
be as good as... a light webserver and a ramdisk. ;)
If you've got a huge amount of content, and want to
accelerate the hottest fraction, squid is still the best choice,
and can be tuned
Hi. I'm in the early stages of designing and testing a config with
multiple aufs cache_dirs on squid-2.6.STABLE3 as httpd accel for a lot
of content, and have a few questions based on what I've observed thus
far:
* x-squid-internal/vary stubs appear to be able to wind up on a
different cache_dir
