MS Bob 11 Posted March 13, 2011 Share Posted March 13, 2011 According to this page and confirmed by Tim Sneath, only 32-bit IE9 has Chakra JIT engine which explains why 32-bit IE9 performs better than 64-bit IE9. I guess even Flash going 64-bit in beta, 64-bit IE is still not a viable option if it comes with a slower JS engine. :( Link to comment https://www.neowin.net/forum/topic/982170-only-32-bit-ie9-has-chakra-engine/ Share on other sites More sharing options...

If read the first few line of the article it does says that. Edit: I was wrong 64-bit doesn't have any JIT engine at all. 64-Bit IE FAQ Link to comment https://www.neowin.net/forum/topic/982170-only-32-bit-ie9-has-chakra-engine/#findComment-593783762 Share on other sites More sharing options...
ObiWanToby Posted March 13, 2011 Share Posted March 13, 2011 Seems odd to cripple 64bit. At the same time, 32 bit browsers work fine. Do other platforms (OSX and Linux) even show an improvement by moving to 64bit? Math or memory usage? Browsers are certainly becoming more and more important, if 64bit helps, then well, this is a big mistake.

If Microsoft continues supporting legacy 32bit processors, part of their customers never going to upgrade. Microsoft is supporting the 64bit IE. When you install IE on 64-bit Vista or Windows 7. Both 64-bit and 32-bit versions get installed. They have chosen to make 32-bit default because of add-ons. You can force IE to run in 64-bit mode but you will loose some add-on support. IE9 in 64-bit is 8 times faster than IE8. Currently there aren't many add-ons that support 64-bit browsers. Flash is an example. (Flash-64 has been in beta since last year) Link to comment https://www.neowin.net/forum/topic/982170-only-32-bit-ie9-has-chakra-engine/#findComment-593783806 Share on other sites More sharing options...
+Zlip792 MVC Posted March 13, 2011 MVC Share Posted March 13, 2011 I also shocked once, I read about it. Maybe Mozilla Firefox 5 will become first nice 64-bit browser but again IE9 s major step from IE8. God thing at least they now support standards.

alexalex Posted March 13, 2011 Share Posted March 13, 2011 According to Microsoft : ?The 64-bit IE 9 RC doesn?t use the Chakra JIT does it? It uses the older, far less efficient one, right?? Sneath replied, ?That?s correct?we put all our JIT compiler investment in this release of Chakra into the 32-bit compiler, since that?s the one that is near-universally used today. The 32-bit browser is the default even on 64-bit systems, since almost all add-ons are 32-bit only at this time. The 64-bit version provides no real advantage, since no browser scenario requires access to >2GB of user memory in a single process.?

Honestly you can run 32bit version of IE9 on 64bit win7 without any issue and since this hasn't come up till now (IE9 ahs been in dev for 12 months!) it seems no one saw much of a difference to complain. Either way it's been hinted that the IE team will jump right back into dev the next version of IE at MiX next month, that version will probably see the 64bit side get most of the work. I agree with them though, in what crazy situation would you need >2GB for a browser process?

MS Bob 11 Posted March 13, 2011 Author Share Posted March 13, 2011 They should at least make it more prominent. Many users who don't know this are likely to use 64-bit IE9 thinking now 64-bit Flash is almost here (still not release version), there aren't any issues with 64-bit IE9 and then they would really be experiencing poor JavaScript performance.

And it's not going to switch any sooner if lazy coders purposely neuter their products because they can't be bothered to work on the development. The simple answer is either provide it, or don't provide it at all. Never do an half-assed job.

And like GP007 has pointed out, if the impact was so big I'm sure this would have been brought up before. But it hasn't. And like he also pointed out they might be working on the 64bit version later on.
