   please go through this squid info and suggest me any changes that r needed to tune my cache ( squid 2.2 Stable 4 )running on redhat 6.1
problems
1> very high pagefaults with disk i/o to total no of http requests ratio , it was around 0.1 up to 400000 to 500000 http requests but inceasing very rapidly
 
2> top command is showing that
total mem ~ 582mb
used mem ~ 578mb
free mem ~ 3mb to 6mb
 
3> i have just added one new cache disk of around 3000MB to it i am sending
my StoreDirectory Status page too
 

my current config is:
1> avg_object_size 10 kb
2> maximum_object_size 2048 kb
3> cache_mem 32 MB
4> cache_dir /cache1 16 256
5> cache_dir /cache2 16 256
6> ip_cache_entry 2048
 

      if u wnat some configuration details of any other tag then i will send it to u
 
one more thing i want to know is that is it possible that squid sends the http request for any object to origin server with ip address of the client that had actually requested that object .
