Squid caching proxy of the Computer Research and Automation Institute in Hungary is a part of the Hungarian academic network caching hierarchy. Sztaki proxy uses iif top level Hungarian proxy as a parent for popular transatlantic domains (.org .com .edu .jp .ca .net .au). The link bandwidth between iif and sztaki is about 10 Mbps. The patched version of Squid was run on Wednesday, October 29, 1997. It was the last day when sztaki was using iif as a parent. We also have statistics for other days.

Warning: This proxy was running Squid with the "double-read(2)" bug that may affect performance of a proxy.

We split our experiments into 6 categories.
