Yesterday I stumbled upon a benchmark by euforic. So today I sort all the benchmark, remove all with high memory usages, and ones with worst performance and end up with this spreadsheet visualization (oh before I forgot, LibreOffice Calc conditional formatting is freakin' buggy).
And if you asked me, what's the best for all case? Just search for one that have the most green. Denco seems to have consistent performance, and FYI the older benchmark favors to HttpRouter.
