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 tests localStorage performance against IndexedDB, both acting as an object store. localStorage tests contain JSON stringify/parse methods.
There's a performance penalty for the IDB tests though, as these operate on IDB via a wrapper, so there are are some additional function calls being made.
