on
1:-I had installed squid(rpm) on REHL 5 installed on vmware . Since this is production environment its performance is slow as compare to direct connection to internet due to which client are facing problem.
2-: Second issue which I am facing is there are few websites which did not upload in correct format but when we remove proxy page uploaded correctly

Please resolve my both issues as soon as possible

Thanks

Ok number of users is not that high 115 is normal, other settings are normal, although you have not implemented any performance tuning but it still should be ok

So I assume that you have no ACLs. , ok your cache_mem seems to be high, another thing to check is if you are using any SWAP space (if so squid will perform poorly)



post the output of the command
