The function you're pointing to is called by every Qt program on Windows (even non-gui programs) and they all would "slow down Excel".
IMHO the only thing you can try to find out what's wrong is reducing your program step by step until you get a small example that demonstrates the problem. I'm pretty sure that you already will find the source of the problem while doing this. ;)
