 Install a caching DNS server on your server and have Squid use it so as to cut down on your DNS requests.  This [[http://www.httpcompression.net/howtos/pdnsd.html|how-to]] may be helpful.

-===== Squid Refresh Patterns - Microsoft =====
-Sites like Microsoft’s windowsupdate.com, which virtually all Windows PCs update their OS from, are among the most bandwidth-intensive sites on some networks.
-Unfortunately, they are not cacheable because they offer partial responses (http return code 206), which Squid presently does not cache.
-Where you have control over the client machines, you can install Microsoft’s Update Server to handle caching for windowsupdate.
-If you cannot use the Update Server, you can use Squid’s delay pools — a bandwidth management technique — to limit the portion of bandwidth that windowsupdate consumes during your peak periods.
-The clients will then have to be online during off-peak periods to complete their updates.
-Below, we configure one global delay pool at 64Kbps (8KBps).
-Traffic for which the ACL of destination domain is windowsupdate.com during the peak period of 10:00-16:00 will be limited to 64Kbps.
-<code>
-acl winupdate dstdomain .windowsupdate.com
-acl peakperiod time 10:00-16:00
-delay_pools 1
-delay_class 1 1
-# 64 Kbit/s
-delay_parameters 1 8000/8000
-delay_access 1 allow winupdate peakperiod
-</code>
-After making changes like the ones above, Squid’s byte hit rate increased from about 8% to between 26-37%.  If you are doing 33%, it means a third of all traffic is coming from your cache, and not from slower links across the Internet.
