hpi

This project, called hpi (HTTP Performance Investigation), is designed to test how fast different web servers run when using different versions of the Ruby programming language. It exists to answer a practical question: if you are building a web application in Ruby, which combination of server software and Ruby version will give you the best speed?

At a high level, the project runs a series of tests that push web servers to handle incoming requests, then measures how quickly and efficiently they respond. Ruby has several different implementations (like different engines that can run the same code), and there are multiple popular server programs that accept web traffic for Ruby apps. This project mixes and matches those options to see how they compare side by side.

The primary audience is developers or engineering leads who are choosing the foundational pieces of a Ruby web application and care about performance. For example, a team deciding whether to upgrade their Ruby version or switch their server software could use the findings to make an evidence-based choice rather than guessing. It provides a structured way to see the real-world speed differences between technical setups.

The README is extremely sparse and does not go into detail about exactly which servers or Ruby implementations are tested, nor does it explain the methodology behind the measurements. Based on the primary language being Ruby, the project itself is likely a collection of Ruby scripts and configurations designed to automate these tests. However, the specifics of how the results are generated or reported are not documented in the provided overview.
