With same multi-squid-instance configuration, same Linux distro, and
different hardware, AMD Opteron gets more balanced CPU usage, while on
Intel Xeon just one CPU core running out, others still too idle, about
5%-15%. When that core runs out, simple TCP SYN check on service
failed occasional.

I'm still trying to get this problem resolved...:-( Now I'm trying
