Yes, then we could make our programs run faster with:

Well, you must not have done the actual benchmark. I did, and I found that on MSWin32, it's gt that is faster, not lt. So the correct way to optimize this comparison is: 
if ($^O =~ /^MSWin/) {
    $comp= $a gt $b;
} else {
    $comp= $b lt $a;
}
