Could you provide more details? Output of cache manager's "info", 'ps',
'vmstat', hardware configuration?

The Renater national cache <> uses DU 4.0 on an
AlphaServer 1000.

1.1.10 is fine. We just upgraded to 1.1.14.

Three rules with Squid, specially on DU (it's a bit different on Linux):

1) Add RAM
2) Add RAM
3) Add RAM

Squid is a hog. Memory really used depends on the malloc you use and
wether it leaks or not (we found that GNU malloc is a good choice *and*
we restart Squid every week), depends on the size of the memory pools
(cache_mem) and depends on the disk size (I bought more disk than the
memory could use, I now have to beg for RAM).

CPU : any 386 will be more than enough (our cache, with twelve HTTP
requests per second - and more ICP - runs at 30 % of the CPU limit).

Swap: do not even think about it. Response time will dramatically drop
when Squid swaps (I tried!).
