Why are you measuring under Windows to see what will happen on Unix?
If you've only got one machine to play with, why not boot off a LiveCD (like Knoppix) and measure your code (or a key subset) under Linux?
Might not be the same OS your ISP is using, but closer to Unix than Windows?
Might make absolutely no difference, but at least you might be a bit closer to comparing apples to apples rather than apples (Unix) to oranges (Windows) ...
