Does OpenCV 3.4.x perform better(execution time) in release mode?

So I've built OpenCV 3.4.1 in Release mode with default flags. Does this make the build any different than if I built in Debug mode? I have a large codebase that utilizes OpenCV core libraries, and changing the build to release mode has not made much difference. I'm wondering If I've done something wrong or forgotten something during my build - perhaps some flag that should be set for enhanced performance.

Here is a log of my Release build config.
