New issue 2321 by [email protected]: Math.pow(10,1) / 100 ridiculously
slow (only) on nodejs
http://code.google.com/p/v8/issues/detail?id=2321
Division with a result of Math.pow cripples performance. However if I add +
0 to the result of Math.pow, it's okay again. This only happens in nodejs
v0.8.4. in chrome browser it's fine.
$ node
measure = function (fn) {now = new Date(); i = 1000000; while (i--) {
fn() }; console.log((new Date() - now) / 1000) }
measure(function() { Math.pow(10,2) / 100 })
// => 0.631s
// Quickfix:
measure(function() { (Math.pow(10,2) + 0) / 100 })
// => 0.014s
Issue on nodejs
