- We use Squid on a Sun Sparc 5 Solaris 2.6 machine. We have 2 * 4 GB
cache-disk and 128 MB memory.
- We have a lot of performance problems. Response to an normal page (in
cache = 180 bytes/s). We have an 2 MB connection to the internet. One
and a half week ago we had the same problem, cleaning the cache helpt
(for a week).
- netstat -a | wc -l = 658
- This is a one task machine, only Squid is running
- We have a potential 1200 users
- cachmgr.cgi show's
