RE: [squid-users] Hardware requirements

Sure, we have 3 of these clustered in an all-sibling reverse-proxy setup.

2 x 3.0 GHz Xeon 64-bit
2 GB DDR-400 RAM
1 x 80 GB WD HDD
3 x 400 GB WD HDD
..running Fedora Core 4 x86_64

Squid is 2.5 STABLE12 with epoll and collapsed-forwarding patches

Configured with: --enable-async-io=32 --enable-snmp --enable-htcp --enable-underscores --enable-epoll

As you can see we use: htcp,�aufs (with noatime options on the mounts) and snmp for monitoring via cacti. Here are some items from squid.conf:

http_port 80
icp_port 0

Gregori,

Can you give me the details on your entire setup? I have a 3.4GHz Xeon with 2GB memory and 100GB cache and with 200+ req/s my CPU is pinned. I have a transparent cache with WCCP and don't use any ACLs except for SNMP.

Thanks,
 Bryan

That should be fine, however I would recommend a lot more diskspace�for the cache. Each of our servers are 3GHz Xeon, 2GB RAM and 1TB of diskspace - they each push 130mbps of flow without any problems.

We have 2-12 mbits of traffic flow.

Is scsi320 72MB + RAM 1GB + Xeon 2.0GHz server enough to proxificate
it transparently? Or we need more processor/RAM? Or we need to
balance flow between 2-3 servers (because of non-SMP architecture of
squid)?

Thanks.
