Varnish is a reverse Web accelerator designed for content-heavy dynamic web sites. In contrast to other HTTP accelerators, many of which began life as client-side proxies or origin servers, Varnish was designed from the ground up as an accelerator for incoming traffic.We actually claim that Varnish is ten to twenty times faster than the popular Squid cache on the same kind of hardware!

-We were extremely pleased to see how well Varnish handles spikes in traffic. Without Varnish, our machines would be brought to their knees when theses spikes occur (we have tested this).
