Build Configuration: Optimize for Speed vs Optimize for Debugging

[mosonu]

Hello,
I’m testing a PID controller for a quadcopter. When I compile the application with the optimize for speed then flash, I notice that the PID response is slower than when I compile with the Debug optimization .

What could be the reason?

Hi

This sounds both interesting and  strange to me. Do you have any numbers to show this? It would also be interesting if you see the same if you use no optimization
