[squid-users] Squid Under High Load

I finally got Squid 2.6STABLE9 setup and running on CentOS. I am
using my Mikrotik router to DST-NAT connections to it.

I installed Squid with these options.

./configure --enable-linux-netfilter --enable-storeio=ufs,aufs

Setup to use aufs. Only changed basic things in squid.conf.

Only been running experimentally for little while and seems to run
fine at first. After routing hundreds of IP's to it though it seems
to stop responding. One of the things I see in the log file.

2007/01/26 09:59:19| WARNING: All dnsserver processes are busy.

2007/01/26 09:59:19| dnsSubmit: queue overload, rejecting www.musicgiants.com

I have bind running on this box as well for a DNS server. Are there
any tweaks I should make to support a large number of users? 3 Class
C's. Some dialup mostly wireless broadband. It connects to currently
6mbps Internet connection soon to be 10mbps. Also, it has 1Gbyte DDR2
with SATA drives. Do I need more RAM?

Thanks.
