Re: [squid-users] squid with FreeBSD 6.0 tuning

Hi,

I'm seeing some unusual cpu usage pattern in our cache farm as well. we
have 3 cache connected to one wccpv1 router:

1. 2.66GHz P4 with 1GB RAM, 128M squid mem, 12GB aufs cachedir. RHL 7.3

All of the above squid boxes receive equal amount of hash bits from wccp.
can you link anything ?? Thanks.
