Morning Daniel, this is a VERY informative video! I have watched MANY videos on how to evaluate query performance with timers, but none of them referred to the QueryPerfomanceCounter API you are using. I even learned a new way to clear the immediate window. Again, great video, thanks for taking the time to post it...

Excellent work and presentation. The same goes for the many other topics on this channel. The QPC approach appears to be a cleaner version of Charles Williams' "Micro timer".

Hello This is very interesting. Is it possible to get a copy of your QPC code, please?
