Java programs might not run in debugger very well either, depends on where and how you place breakpoints.

However I'd be glad if profilers (and notably memory profiler) would slow down a Python program only as much as valgrind does C.

I noticed that java with a connected debugger can be very fast even with breakpoints, but stepping over can be very slow. Which is a big weird, since "step over" is basically just putting the breakpoint on the next line.
