How much cleaner could it possibly be?! But perhaps that’s because it’s in VPC. Is this test highly memory or CPU dependent? If so, I guess that explains VPC.

So I closed all my tabs in my main 9.01 Opera (outside of VPC: machine 3GHz P4 with 2GB RAM), and without restarting it got this:

Try/Catch with errors 15
Layer movement 141
Random number engine 78
Math engine 125
DOM speed 63
Array functions 62
String functions 672
Ajax declaration 16
Total Duration 1172 ms

Ran it again, got this (seriously):

Try/Catch with errors 0
Layer movement 47
Random number engine 93
Math engine 110
DOM speed 62
Array functions 63
String functions 93
Ajax declaration 32
Total Duration 500 ms

Closed Opera, ran it again, and then got this:

Try/Catch with errors 15
Layer movement 63
Random number engine 94
Math engine 109
DOM speed 47
Array functions 78
String functions 156
Ajax declaration 47
Total Duration 609 ms

Ran it again, got this:

Try/Catch with errors 16
Layer movement 78
Random number engine 78
Math engine 109
DOM speed 63
Array functions 62
String functions 172
Ajax declaration 47
Total Duration 625 ms

Opened all my tabs (15-20) again and saw it go from 1437 to 1640 to 1125 to 1250 to 1094.

Perhaps this test is severely affected by what else you have running. I didn’t try closing down every last thing, including tray apps, but perhaps if I did I’d get good numbers. Not that I’d ever do that in real life.

In summary, I think this test is whacked.

On my Linux w/ Gnome 2.14 the String function test is also *reaally* slow. When about 30 tabs are open (and music player in the background eating a bit of CPU) the string test takes about 3000 msec on first run and 1000-1500 msec on subsequent runs.

My IE6 must be screwy somewhere check this:

Opera:

IE6:
It gets hung up on two stages!

Pretty much a fresh install, as i recently formatted the partition, as well all patched and up to date … wierd eh?

Good thing i dont use it, so i dont really care

While it would be next to impossible to get proper website to include such code, an example of what I mean is the recent TiddlyWiki beta. This is a very complicated client-side script. For testing purposes during development, they added a performance check.

On my system, Opera usually takes 800ms to process the script, Firefox about 1000ms (25% longer) and IE about 1140ms (42.5% longer).

Another good thing about that page is that you can download it to your computer and totally eliminate network latency from the numbers.

I consider that a much better test than some arbitrary benchmark.

Any Linux Opera users check out your CPU usage while running this, and then compare it to other browsers (such as Konueror).

I’l been trying to get them to fix those rendering issues. I can’t tell if it’s doing any good though…

Also, yes Gmail does seem to slow it down some, but my 375ms just went up to 610ms. Still not bad!
