Running a program in Debug mode is incredible slow

Another "debugging break" is the use of method entry/exit breakpoints.

Did you try to remove all breakpoint definitions once?

Sometimes i think Eclipse is getting out of synch with some of its internal/displayed state. Perhaps you should try to setup a new (not copy) of your workspace. This sometimes helps me to recover from spurious features.

This is how you can remove all breakPoints

Eclipse -> Run -> Remove All Breakpoints - for removing all Breakpoints for all Time

Eclipse -> Run -> Skip All Breakpoints - for temporary remove breakpoints

I faced this issue lot of time. Solution is simple, Remove all breakpoints. (Run >> Remove All Breakpoints)

Disable 'Show method result after a step operation'.

I was just running a program in Eclipse debug mode that was almost instant without debugging but when I ran it in debug mode, it was really slow. I went through and deleted a ton of random useless breakpoints I wasn't using and then the program sped up A LOT (200x or so).
