If memory serves, adjustments to the OS need to be made to take advantage of the 64-bit memory addressing. I know some changes have been made to OS X to run on a 64-bit chip, but I'm not certain they've made enough modifications to take advantage of the memory addressing.
I'd be interested to see how this works on Panther. -----Original Message----- From: Jeremy Zawodny [mailto:[EMAIL PROTECTED] To: Gabriel Ricard > I wrote a small C program to test malloc() and see just how much I > could allocate, and I was able to get up to 3.5GB before being cut off > by the OS, which leads me to believe that I should be able to use that > much RAM for MySQL. Yes. I wonder why you got cut off at 3.5GB. I'd have expected OS X on 64bit hardware not to have the weird limitations that, say, FreeBSD or Linux with kernel reserved memory. Something is wonky here... Thanks for the info. I'd love to hear if you're successful getting MySQL to use more than 2GB. I'm gonna hunt around a bit more to see what others may know.
