Without having any look at the code at all, or even a high-level description of what it does and how it is written, nobody is going to be able to help you. Just some questions: Are you using some MMX or SSE instructions on Linux but not on Windows? Are you invoking library calls that are of significantly different speed in the inner loops of the code? And of course, the most obvious: This is on CPUs that are identical or similar enough, right? --tml |
