Nginx now includes proxy_cache. Haven't done any full benchmarks (micro-benchmarks like ab don't tell you much about real-world performance). But we replaced Squid anyway, just to simplify the stack. It "feels" faster, probably because of the reduced latency.

Interesting. So with nginx we can no do basic load balancing, proxy caching, static serving and dynamic proxying. It's catching up with apache in features but with speed.
