64-bit performance

yck — Tue, 24 Jul 2001 02:56:01 GMT

Hi all, i have make an experiment to compare performance between 32-bit and 64-bit application. However, i found that 64-bit performance is 1% slower than 32-bit on large data sets that runs for more than 30 minutes. Is this correct? What else to look out for?

For your information, application that i try is involve with many number crunching, or arithmetic computing.

Thanks.

But what i means is.. is that realistic that performance of 64-bit application is not much different compare to 32-bit application? I means speed of application (involve arithmetic computing). Cause from what i read from 64-bit article is 64-bit application have much performance compare to 32-bit application.

Thanks.
