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
Speed tests regarding xhr polling.
<script>
var pool = [],
newXHR = function() {
return new window.XMLHttpRequest();
};
if (window.ActiveXObject) {
newXHR = function() {
if (window.location.protocol !== "file:") {
try {
return new window.XMLHttpRequest();
} catch (xhrError) {}
}
try {
return new window.ActiveXObject("Microsoft.XMLHTTP");
} catch (activeError) {}
};
}
</script>
Ready to run.
