these two options will decrease your connections and therefore descrease the cpu usage of select/poll system call. If you have not many small files to transfer in one connection between the client and squiid, you will benefit from the "client_persistent_connections off" option. Also I suggest you to close client_db if you use squid as reverse proxy or accelerator, because the hashtable for collecting client information only has 467 buckets, compare to the potential user on the internet, it's too small. and the collision of the hashtable access will eat up your cpu day after day.
