Firefox and slow JavaScript in 64 bit
Hello!
I've installed 64 bit Archlinux on my laptop. I noticed poor JavaScript performance with firefox. I had 32 bit linux before. I ran benchmark from this site: http://www2.webkit.org/perf/sunspider-0 … pider.html and I got these results (approximately) - Less means better:
firefox 3.0.11 - 3200 ms
firefox 3.5rc2 - 1500 ms
midori 0.1.7 - 1400 ms
But now on 64 bit, firefox is slown down:
firefox 3.0.11 - 3800 ms
firefox 3.5rc3 - 3200 ms
midori 0.1.7 - 860 ms
I tried several builds including self compiling, but results are the same 
Well, it's not that big issue, because browsing is fine. I'm just curious why there is such difference. I thought 64 bit would be even faster...

Re: Firefox and slow JavaScript in 64 bit
Same thing here.
Firefox is significantly slower than midori.
Here "FROM" is firefox 3.0.11, "TO" is midori 0.1.7. Both are from extra.

Re: Firefox and slow JavaScript in 64 bit
Thanx for replies. I will wait until firefox 3.5 is in extra, which will be soon. Hope it will have new tracemonky and better score. If not, I will try firefox-hg from AUR.
EDIT:
Well, problem is still there :-( I hope they will enable new tracemonkey in 64 bit version some day...

Re: Firefox and slow JavaScript in 64 bit
AFAIK there is no code for 64bit tracemonkey in FF 3.5 final, and there is not yet a definite plan on when it will be there. so it could be with some of the minor 3.5 upgrades or it also could be with 3.6 or whatever will come after 3.5. Mozilla apparently considers the 64bit userbase to small to make 64bit tracemonkey a priority (thats at least what I read on some blogs/comments). Maybe its time to finally make the switch to midori ^^

Re: Firefox and slow JavaScript in 64 bit
Another thing you can do is installing the "firefox32" package from AUR + lib32-flashplugin and use that instead in the meantime.
At the moment 64 bit browsing still sucks because of low interest by the developers of both browsers and plugins (flashplayer).
I've noticed a lot of compiling problems on firefox on my 64 bit system even with past releases and the 64 bit flash player is far from being competitive with it's 32 bit counterpart (it's much slower on HD videos and such).
I hope this will change in the future

Re: Firefox and slow JavaScript in 64 bit
or use opera-snapshot from archlinux.fr. It has a QT4 build of opera10beta ..... which is really really fast on my pc.

Re: Firefox and slow JavaScript in 64 bit
openjdk and jre are somethin completly different than javascript. Tracemonkey probably will not be enabled even for firefox 3.6 x86_64 and is definitly not available in firefox-hg.

Re: Firefox and slow JavaScript in 64 bit
If you need super-fast javascript in a 64-bit browser, it seems Google is doing something right:
opera10 x86_64: 3306.2 ms
firefox 3.5.2 x86-64: 1985.2 ms
chromium-snapshot-64: 428.4 ms
Javascript in chromium is 4.63 times faster than in firefox on my 64-bit system. And chromium blows opera 10 away.
Not sure if it makes a bit of difference in actual browsing...

Re: Firefox and slow JavaScript in 64 bit
Lol my results are worse:
firefox-pgo 3.5.3: 4378.0ms
chromium-snapshot-64: 726.6ms
Midori: 724.4ms
BTW:
Konqueror....I never though you were so slow...: 5114.0ms
Opera 10...and I thought Konqueror was slow...: 6295.0ms
My conclusions:
1. Firefox is faster than people make it out to be (shut it, Opera fanboys!)
2. Webkit kicks any other rendering engine's ass 
3. I still don't care, Firefox and its extensions FTW.

Re: Firefox and slow JavaScript in 64 bit
So it is working in TRUNK:)
Too bad 3.6a2 hasn't merged TM code, we have to wait for 3.6a3.
