 Posted: Thu Mar 26, 2009 10:30 pm Post subject: Very slow javascript execution |
 |
|
When I run firefox, javascript can sometimes be painfully slow. A friend of mine suggested, that it could be because of me not having graphic card support. But, well I do and I can run hapilly some openGL examples (And it doesn't complain, that I don't have graphic support, as it used to, when I didn't). So, do you have any idea, what might be the reason for a very slow js execution? I'd love to change this, because this actually affects my daily usage of a computer

To quantify "slow", run this benchmark and post the results:
http://webkit.org/perf/sunspider-0.9/sunspider.html
If you have multiple browsers installed, try it on all of them.
Also, post your "emerge --info" and "emerge -pv mozilla-firefox". |

Whoa! I didn't expect opera to run nearly twice slower!
