So I have a question for those who understand developer speak and MySQL
builds and so on...

Apple announced their new OS earlier this week, including this information
on the improvements to 64 Bit version using the G5 processor:

http://www.apple.com/macosx/tiger/64bit.html

One of our biggest problems to date on our G5 servers is despite the bulk
ram we have installed, the current Apple OS isn't really 64 Bit so we can't
give the InnoDB caches more than 2Gb of ram, and thus there are always no
empty pages.

This statement from Apple stops short of saying the OS was fully 64 bit...
But I think they are saying that apps such as mysqld will be able to call
larger chunks of memory, which is what we want.

Between MySQL's strong Apple ties and the build engineers working on MySQL
binaries and the knowledgeable members of this list can anyone interpret
this statement from Apple and tell us if we will be able to increase the
InnoDB cache settings to take advantage of the memory in the systems?

As our application uses many different databases and any application server
only ever speaks to one database I am seriously considering running multiple
instances of MySQL on a single machine with different databases - but it's
aheadache to administer... I'd rather use my 65 bit hardware and MySQL's 64
bit builds and use the memory in the machine in a single instance...
Comments welcome.

Best Regards, Bruce
