Which OS/webserver combo server static web page in shortest time under no load?

Preface

Full page load time measured using pingdom is below expectations on a highly optimized page (Pagespeed score 97/100).

Next trial-and-error step was to test using different os/webserver combos. A relative old Windows 2003 IIS box served the static page almost 4 times faster (0.30s) than two different Apple boxes running Mac OS X build-in Apache (1.15s). Where Rackspace/Akamai CDN using Nginx loads the full page in 0.08 seconds or slower.

Question

Is anyone aware of some published test results or benchmark that compares the full web page load time of different os/web server combos?

Requirements:

• using static content,
• not measured on localhost,
• preferrably splitting: start - connect, connect - first byte & first byte - last byte phases for each hit,
• where the web servers are running on (almost) identical hardware,
• in internet networks that are in comparable distance between testing client and serving host,
• without measuring caching or DNS performance,
• under no load (most webservers have low load not maxed out like most available ben开发者_运维技巧chmarks test)

Looking for a comparison that tries to deliver shortest output times of static content in a real world internet environment where os/webserver combo is the variable.

I suggest to read this decent article about benchmark results: http://nbonvin.wordpress.com/2011/03/14/apache-vs-nginx-vs-varnish-vs-gwan/

Seems G-WAN is the pure winner. I heard many major high-traffic sites switching to this already (since - in most cases - may serve content twice faster then Nginx. Basically allows a delay on hardware upgrades).
