There can be a number of reasons to this

a) Your squid is really running out of file descriptors. This will happen
if you trow a couple of thousand users at a Squid cache without tuning the
number of filedescriptors (see FAQ).

b) Your Squid is overloaded, or most likely your cache_dir is. If using
the default "ufs" cache_dir type then speed will be very much limited by
the speed of your harddrive, and when this limit is reached performance
quickly spirals down. Use "aufs/diskd" cache_dir types, and design the
hardware correctly for the load you are planning.
