Dear all
Any experience using squid as caching in ISP
environment ?
thanks

I'm sure there's much larger ISPs out there and
been using it much longer;
just passing along our info.
We're a small ISP serving around 10k dialup,dsl,cable
modem and MAN subs
via a dual-homed to different ISP BGP WAN.
We loaded squid on a quad core linux box with around 1.2Tb
disk
capacity and 32Gb RAM, using a Cisco 4948 switch and WCCP2
to transparently redirect to Squid.
There were some major hurdles along the way
mostly getting the 4948 to pass the L2 WCCP traffic -
2 IOS bugs and a year in the process) but once that worked
and we got our IPTABLES set up properly, transparent
redirection
has been working quite well.
Some tweaks needed to our Squid config, but with the help
of this list
- particularly Henrik and Amos' posts - at this point
we're very
encouraged by the performance and bandwidth savings
we're seeing on the
system which has only been truly active for around 3 weeks
now.
Again, we're a pretty small shop - so when our old
NetApp Netcache
was no longer able to adequately handle the load, we needed
an
effective, minimal-cost solution which this is
demonstrating to be.
Hope that helps.

Thanks for sharing this. We're doing about 75 requests/sec on a quad-core Xeon with 16GB. Still trying out some different configs.
I have cache_mem set to 2GB and it's working well so far.
It's not even worked up a sweat and has plenty of room for more work.
I'll bet it isn't.
75 is not even close to half what squid was doing in Y2K. :)
If you want to stress it we'd be glad of the results.
