Page Analyzer



Page Analyzer is a web application used to analyze HTTP Archive Files(HAR) and store the results in a database. The project was created for performance engineering purposes, to have an easy way to track common performance issues of web applications over time.
Therefore it also features a compare functionality and several views to analyze the results and the raw data of the HTTP Archive.

The analysis is based on a heavily improved version of the decommisioned YSlow Project, originally created by Yahoo. This provides the whole rule engine that was extended with several new rules.
