Comments on: Javascript engines in 32-bit and 64-bit browsers http://heliologue.com/2008/03/23/javascript-engines-in-32-bit-and-64-bit-browsers/ Sat, 04 Feb 2012 03:16:04 +0000 hourly 1 http://wordpress.org/?v=3.3.1 By: Michael Moy http://heliologue.com/2008/03/23/javascript-engines-in-32-bit-and-64-bit-browsers/#comment-154971 Michael Moy Wed, 26 Mar 2008 19:27:14 +0000 http://heliologue.com/?p=2017#comment-154971 Makoto started work on 64-bit builds in 2003 and I spun my wheels trying to get it to work for a while. He gave me his code in 2005 and I started building them then. I thought that support would come in FF 3 but it was only NSPR support. So I need to either port my 2.0 stuff to 3.0 or ask Makoto for his stuff and then get it to work (not that easy to do). I have a project that I haven't really started, to get plugins to work on the 64-bit browser but I haven't had the time for it. This already exists on Linux. It turns the plugin protocol into RPCs which are shipped to a 32-bit stub that interfaces with the 32-bit plugins. In a sense, it allows a 64-bit program to make calls into 32-bit shareable images. The author of the Linux software indicated to me that he was looking at doing a Windows port but this was early in 2007 so I assume that he's been busy with other stuff. Windows XP x64 edition is a very nice operating system but AMD and Microsoft dropped the ball on marketing and drivers.

I purposely didn't test 2.0 builds because the JS performance is so bad, regardless of platform, but maybe I should just for illustrative purposes. I must say, I'm a bit peeved that Mozilla hasn't bothered to produce x64 builds themselves; I get that most plugins wouldn't work, but that's hardly <em>their</em> problem.

I think that he just did that as a proof of concept and that building with normal compiler optimizations will come down the road. I believe that IE7 is built with PGO which adds a big boost. FF 3.0 on Win32 will use PGO as well. I'd suggest that you give my 64-bit builds a try. I only have 2.0 builds right now. I assumed that FF 3.0 would support 64-bits natively but I'm wrong on that. I do intend to do 64-bit FF 3.0 builds but it will take me a while to get there. I think that the Firefox build that you got from Makoto’s site is unoptimized, and yes, the performance is awful.
