Are 64-bit Binaries Slower than 32-bit Binaries?

Posted by michael on from the glass-half-empty dept.

JigSaw writes "The modern dogma is that 32-bit applications are faster, and that 64-bit imposes a performance penalty. Tony Bourke decided to run a few of tests on his SPARC to see if indeed 64-bit binaries ran slower than 32-bit binaries, and what the actual performance disparity would ultimately be."

    For the most part, there's little need for the extra bits, so you are just wasting computer time processing unnecessary bits.

    Maybe you should all concentrate on making things more efficient, rather than relying on faster processors to make your crappy bloatware look fast.

    I don't care if you are from the GPL camp or even Microsoft, everything out there from both camps is bloatware!

    Computers in 2004 should actually be faster than computers from 1995. From all I've seen, because of the constant bloatware, this is not even the case, and may actually be the opposite.
