"Caching is an important function for a wide variety of Internet-related concerns, as ISPs, educational institutions and corporations all find that it measurably enhances system performance. There are a host of commercial caching products on the market, but perhaps the most popular is Squid, the open-source cache originally produced by the ARPA Harvest project and now maintained by the National Laboratory for Applied Network Research (NLANR)."

"That's why you should be interested in running Squid if you're doing any sort of Web serving. In this article, we'll explore Squid configuration and test its capabilities under real-world circumstances."

"Chances are pretty good that you already have Squid, since virtually every Linux distribution includes Squid in both source code and a precompiled binary (Slackware Linux, for instance, offers Squid in its installation process). You can also download source code by following links from the Squid home page. Squid can compile and run on minimal hardware, but experience shows that a stable Squid cache requires at least 128 MB of RAM and several GB of disk storage. Performance of course varies widely, affected by many factors: CPU, memory, disk, Squid configuration and kernel tuning."
