Your experience is not necessarily because Java is slow. It could just be the applications you are running that are slow for reason that have nothing to do with the language. Swing is probably going to be slower (maybe?) than some native windowing framework. But Java as a language running on the JVM is certainly not slow. I've just been looking up pycharm and it seems that the slowness issues are to do with things like opening files and doing parsing. These things are likely to be slow for anything but the language they are written in.
