Where's the source for the implementations? Of interest to me is the NodeJS instances.. was this single-process, or multi-process via cluster (which is recommended for higher performance). The only source I saw was for the testing framework.

Seems to be using cluster. I'm not surprised that Go and servlets were faster... just surprised to see NodeJS in the middle of the pack position. Though performance isn't the only reason I really like NodeJS
