Benchmarks

Tiny comparison between dlang using Vibe.d, nodejs using express and JRuby with Roda

My point here is to do a benchmark on a real daily use case, such as loading n entries from a DB and showing them as JSON using a normal framework. By normal I mean something that is not too much fancy with early optimisation.

Sql dump

1500 entries in a database selecting only 100

All the benchmarks are made with wrk
