Your question is rather vague. What exactly is slow? Running the application, the time it takes to launch the application?
If it takes a long time to start the application, try going to the Debug menu and select Delete all breakpoints . Breakpoints do not work more slowly under normal conditions, but when you change the code, some breakpoints may become invalid. Having these arrounds can slow it down a lot. So clear all the breakpoints and set only the ones you need.
