Oberhamsi's RingoJs benchmark

RingoJs comes with a HTTP Server and basic utilities to deal with JSGI. Unless you are building something very specific, you will want to use packages to ease web development. With this benchmark I try to shed some light on how much those (beta quality) packages for web development degrade RingoJs' performance. The benchmark tasks defined by this benchmark are simple but can give us an upper limit for the performance achievable in real world projects.

I am using the TechEmpower FrameworkBenchmarks. This benchmark tests web development frameworks by running multiple, standardized tasks at varying concurrency levels. The four tasks are outlined in more detail in the results section.

Ringo and friends

I benchmarked Ringo twice to see how a pure JSGI application, written just with the Ringo standard library, performs compared to an application utilizing all the libraries we recommend for convenient web development. Those
