pokatomnik / node-cpu.js
Created August 28, 2017 01:15
This very simple example demonstrates why heavy CPU tasks is really bad idea for node.js (and browser javascript VM, of course)
function load () {
for (var i=0; i<60000; ++i) {
for (var j=60000; j>=0; --j) {
a = i*j;
}
}
}
function cpuConsume(count, cpuLoadFunc) {
var num = 1;
