How about that ?


******************************
64bit is generally slower than 32bit. The only benefit of 64bit is 
non-segmented addressing of several gigabytes of data. If you don't 
need that then 64 bit adressing is just overhead.

It's an urban myth that 64bit is faster than 32bit, like people assume 
a 2GHz computer is twice as fast as a 1GHz computer.

That is also why Apple have been reluctant to make a 64 bit Mac OS X, 
since the people who actually need it already buy AIX instead. Ditto 
for Windows.
