SVSquid caching proxy is a top level server of the NLANR Caching Hierarchy.

The patched version of Squid (v1.1.16 with the "double-read(2)" bug present) was run on Sunday, October 19, 1997. This day may be compared with the days when the bug was fixed. Note, however, that these measurements were done during weekend. We also have [less representative] results for earlier days.

We split our experiments into 6 categories.
