jsPerf.app is an online JavaScript performance benchmark test runner & jsperf.com mirror. It is a complete rewrite in homage to the once excellent jsperf.com now with hopefully a more modern & maintainable codebase.
jsperf.com URLs are mirrored at the same path, e.g:
https://jsperf.com/negative-modulo/2
Can be accessed at:
https://jsperf.app/negative-modulo/2
This is a simple rendering speed test between the most popular libraries/frameworks. I added in Mithril because it's a newcomer with some promise.
Added Mercury...
UPD: ember 1.6.1
Added Knockout Rate Limiting http://knockoutjs.com/documentation/rateLimit-observable.html
UPD: React 0.11.2
