"Is your network's T1 line just not cutting it anymore? Or does
your web server need a boost? In this article I will be examining
how you can speed up your office Internet connection or web server
with a Cache server. A Cache server works by storing frequently
used web pages locally. So then when a web page request comes in,
it simply grabs it locally if it is cached. This is all done
transparently, so the user would only perceive the performance
boost. In addition, it can cache various different types of data
such as web pages, FTP sites, and gopher traffic. Plus, it can
accelerate your web-server by sitting between the web server and
the Internet. It then will cache web-server requests, and reduce
the web server's workload. The performance boost varies between
traffic trends, but we received an average cache-hit rate of 54% in
our labs. Which means our Cache server was off loading half the
traffic from our web servers, and Internet connection. So what
do you need?"
"To construct our Cache server we used Squid Proxy/Cache
software. The Squid project is an open source Proxy/Cache system
available for download on there web-site at:
On the hardware side we decided on the RM Internet Server Appliance
(http://www.rauchmedien.com) which comes preloaded with Squid.
Since Squid is memory intensive and does not require an extremely
fast CPU, we opted for a 566mhz Celeron with 512mb of ram. Plus,
the RM Box comes standard with a fast 20gb 7200 rpm ATA 66 Hard
drive for cache storage."
