Re: squid becomes very slow during peak hours

I wonder if your problem might be diskd.

At one time, diskd was hailed as a great way to speed up a cache, 
but that was back in the days when caches had a small fraction of 
the load they do today. Nowadays, it appears that diskd's overhead 
creates a huge bottleneck.

Have you tried COSS or AUFS?
