Hello!
I've written a simple MediaWiki Benchmarking Tool that runs in the browser and can export the results to several data formats. It uses the MediaWiki API, so it measures just the parsing time.
Maybe it's useful to some, so I've open sourced it at GitHub: https://github.com/Fannon/MediaWiki-Benchmark
Or you could try/use it online: http://fannon.de/tools/mediawiki-benchmark/
Any Feedback is welcome ;)
Greets, Simon
