I am using Squid version 3.1.20 running on
Intel I7 processor with 16GB RAM. Even on connecting a single client I
could able to reproduce this problem.

What version of squid are you using now?
Squid 3.1.20 is very old and it is recommended to use newer versions.
If you are having specific troubles I think you figure out the issues pretty fast.
What hardware are you using for you squid? is it a VM? RAM? CPU?Disk?
How many clients? Have you used the squid cache manager interface?
My first suggestion it to try and use squid 3.4.14 just to make sure you are on something more current then 3.1.20.

Hi ,
we have been using squid 3.1.20 comes with debian wheezy 7. We could see
there is a peformance hit in http traffic when we use Squid.
For each HTTP GET request coming from client to proxy server, Squid takes
nearly 2 seconds to generate HTTP GET in order to establish a connection
with server.
There is always a ~2 second delay between the request coming to our system
and going out of Squid. Suppose if a page has lot of embedded URL's it's
taking more time with squid in place.Suppose If I disable squid the page
loads very fast in client browser.
What could be the reason? Do I need to tweak any configuration for this?
The first page request always loads slow with Squid.
