New issue 177 by [email protected]: Speed congratulations
http://code.google.com/p/v8/issues/detail?id=177
I have adapted a simple test code containing loop, math and dynamic memory
allocation for Javascript.
These are the test results:
IE 8, Beta 2 70 Seconds (about double as fast as IE 7)
Lunascape5 64 Seconds (Alpha Version 5.0 alpha3)
Firefox 3.0.1 32 Seconds
Firefox 3.1b1 27 Seconds (TraceMonkey JIT-Engine activated)
Safari 3.1.2 32 Seconds
Opera 9.61 27 Seconds
Chrome Release 3.6 Seconds
E.g. Chrome is many times faster than the competition.
function SpeedTest()
{
var i, s, startTime, endTime, nRes;
startTime = new Date();
i = 0;
do
{
s = String.fromCharCode(i);
s += "Hello world";
} while(!( ++i > 255*255*255));
endTime = new Date();
nRes = endTime.getTime() - startTime.getTime();
return nRes;
}
We are using a script engine for our 3D online world.

This engine needs 1.2 seconds for the same test. That means there is still
room to make Javascript about three times faster.
