[Ardour-Users] 64bits

[sonofzev at iinet.net.au]

I have run both 64 and 32 bit for along time. 

I have never been able to pick a perceivable difference in performance (even with
8GB of RAM).... 

I have noticed however software compatibility for many linux audio apps is better
in 32 bit (still).. which is disappointing but my production system is 32 bit and
will be until this situation changes.

conditions of the tests not being clear enough (32 or 64bit userland?). Anyway I
think there are clear benefits in using your whole processor and architecture. My
concern is mostly about compatibility and stability of the software. Still have
the feel that most tests have been done on 32bit environments, and that's why I'm
asking here.

 How did that not raise a big red flag for the person performing the tests?

I've learned that what you get is to use all registers in the CPU, which are not
used when running 32bit soft.
