  I don't think is surprising that nginx and lighttpd are faster than Yaws.  erlang is not really a language to just push bits from disk to network.  It doesn't seem optimized for it either, either the runtime or the language.  erlang doesn't have a lot of low-level IO primitives to really push bits fast.  And it probably won't, since erlang is more portable than nginx and lighttpd.
