Squid: Bypass proxy for Private Address Space

[MrFixit]

Hi,
I am sorry but I am very new to pfSense and all the packages so I have a qwestion about squid, What is Bypass proxy for Private Address Space? Does this mean that my client computers with private address will NOT proxy web sites when I look up say www.microsoft.com for example?? I am trying to tune squid because web pages seem to load slower with squid running. I am on current hardware Atom D525 with 4 gigs of ram and a 120GB SSD hard drive.

Just to sum up what I am asking, I just want to know if I should enable the "Bypass proxy for Private Address Space"? and if I do enable it will all request for websites out on the internet still be cached for example www.google.com, www.pfsense.org, amazon.com, ect?

If the destination is private space:
192.168.0.0/16
172.17.0.0/12
10.0.0.0/8

Then this traffic will bypass proxy. Private address space is not available on the internet.

If you have different subnets on your LAN and one subnet with a web server (apache) then it probably makes no sense to user your proxy and cache your own webserver.
