Hello all, I have this topology (http://alexm.unetvale.com.br/squid.png), and the settings below from my squid.conf. 'Everything is working fine', but sometimes the load of the cpu is very high, and I can't find where is the problem. I suspect from the fact that's I have 2 large cache_dir on each process, and this is generating the delay. Today I had to format all caches_dir, and so far I have not this problem. My question is, Can squid slow down, when used with large cache_dir, and they are close to 80% of use? /CLUSTER1 and /CLUSTER2 are separeted hard-drivers - (sas 15K) - just for cache, no system files, and fs type is ext2. I have close to 400 requests/second on Process2, and 200 requests/second on Process1.
