Re: [platform-swt-dev] Why Java Visual Applications is very slow on Mac OS ?

VM's running in "pure" 64-bit mode need to move twice as much data per pointer, which would tend to make them slower; this is offset somewhat on x86 machines by having more registers to work with in the JIT, and some VMs use compact representations for pointers that further increase performance. In any case, your program may or may not be faster, depending on what it does. The biggest benefit of 64-bit VMs is the *size* of program they can run.
