NTFS r/w in Snow Leopard

Don't use the 64bit kernel. If the 32bit kernel works for these
3rd party things then use that instead. If they don't work with
the 32bit kernel then you will have to wait until Snow Leopard
compatible versions are available.
What are you hoping to achieve with the 64bit kernel?

Dave

Starting to 64-it kernel mode won't make things faster. That is, there is no advantage to running 64-bit software (or 32-bit software) in 64-bit kernel mode. However, a great deal of 32-bit software will run in 64-bit mode. The disadvantage of 64-bit mode is that all 32-bit software (e.g., Photoshop) will not run in this mode--so if you suddenly decided to run Photoshop, then you'd have to reboot.

From another perspective there is no disadvantage to running all software in 32-bit mode (which is good news for those with 64-bit processors and without the ability to boot into 64-bit mode). The point is that 64-software invokes 64-bit processing even if run in 32-bit kernel mode.

To demonstrate what I say check out the results of this brief test. I have both Geekbench 32-bit and 64-bit. I made five benchmark passes for each of the four possible combinations of Geekbench “bitness” and Sno kernel mode (e.g., 32-bit Geekbench and 64-bit kernel mode is one such combination). Below are the Geekbench averages for each combination.

(1) 64-bit Geekbench run in 64-bit mode--4,268 avg of 5
(2) 64-bit Geekbench run in 32-bit mode--4,264 avg of 5
(3) 32-bit Geekbench run in 64-bit mode--3,910 avg of 5
(4) 32-bit Geekbench run in 32-bit mode--3,907 avg of 5

Note that there is no significant kernel-mode-related difference in performance for 64-bit Geekbench. Same with 32-bit Geekbench.

Yes, faster but at the expense of some other functionality you wanted.

Dave

Not faster. 64-bit programs are run exactly the same way whether one starts in 64-bit or 32-bit kernel mode. See my prior post.

I saw your post... but Mr Cocktail believed his system was faster (with no
evidence to support the claim). I simply commented that he may have a
faster system but that it now has less functionality. His choice as to what
he wants -- speed or functionality.

I have also read all the other threads with regard to the 32bit/64bit issue
and that was why I asked him what he hoped to achieve.

Dave

No problem. But, you intimated on both of your last two posts that his machine might actually be faster in 64-bit mode, and, therefore, that he has a choice/trade off to make. But, he actually doesn't have a choice logically. He should run in 32-bit mode and have the best of both worlds.

And, OP, have you ever noticed how people put a new, louder muffler on a car and claim that they can perceive the muffler to have made their car faster (i.e., because they want it to be faster having put the muffler on, and then talk themselves into perceiving it to be faster when it just isn't. Same with 64-bit mode. If you don't think what I say is true on your machine, then get 32-bit Geekbench and perform the test I did on your machine.

OK, I shall stop intimating in future 😉

He has the choice of perceived fastness or functionality.

Dave

That was worth reading just for the entertainment.
Cheers 😉

I like it too. You get 3: !http://homepage.mac.com/donv1/.Pictures/AniGifs/flowercool.gif! !http://homepage.mac.com/donv1/.Pictures/AniGifs/flowercool.gif! !http://homepage.mac.com/donv1/.Pictures/AniGifs/flowercool.gif!
