Try recompile everything in "release mode", or with optimization flags such as "O2" or "O3".

Besides that, what is your code? Your processor/environment? Because right now, no one can tell if your code contains a loop like this one:

for(uint i=0;i<2147483647;i++){

    int for_nothing = 2+2/2*2;
    for_nothing= sqrt(for_nothing);
}

running on an old 386, which could slow your execution ;) I am pretty sure this is note the case; but how can we know?
