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
Tiny performance test to see how much a division costs when projecting 3d points to screen.
var focalLength = 3.015;
function slow(x, y, z)
{
return {x: x*focalLength/z, y: y*focalLength/z};
}
function fast(x, y, z)
{
var k = focalLength/z;
return {x: x*k, y: y*k};
}
Ready to run.
