G-WAN is a web server with scripts in Asm, C, C++, C#, D, Go, Java, Javascript, Lua, Objective-C, Perl, PHP, Python, Ruby and Scala.

G-WAN is a (freeware) web application server first published in 2009. The gwan.com site presents the G-WAN API, answers FAQs and also publishes many benchmarks in various programming languages.

G-WAN supports scripts in Asm, C, C++, C#, D, Go, Java, Javascript, Lua, Objective-C, Perl, PHP, Python, Ruby, and Scala (click on a language link to show a benchmark).

An old performance comparison with static servers was done by an academic: http://nbonvin.wordpress.com/2011/03/24/serving-small-static-files-which-server-to-use/

A more recent benchmark (on 1/2/4/8 CPU Cores) - also made by an independent third-party - compares Apache 2.2, Apache 2.4, Nginx, Lighttpd, Varnish, Litespeed, Cherokee and G-WAN: http://www.rootusers.com/web-server-performance-benchmark/
