However, the performance should very similar, if not the same. How did you find out the difference? For proxy cache, separate disk should be used. > > cache_dir diskd /usr/local/squid/cache/cache1 5120 16 256 Q1=128 Q2=100 > > cache_dir diskd /usr/local/squid/cache/cache2 5120 16 256 Q1=128 Q2=100 > > I'm confused.

Not if he uses LFUDA replacement policy and decent cache size. While he has 10G, that will a waste... > So your df above was from the old box? Why not show the new unit? > As someone else suggested.

I have one (yet) such proxy, system and other data are mirrored, but I use rest of space proxy data as two separate cache dirs on two separate disks. > > After 10 minutes squidclient mgr:info return me 70 clients and the > > speed connection goes very low for the users. > > Perhaps try a netstat to see if you have too many users hanging on.
