pycharm running way slow

Question

I\'m a big fan of PyCharm by JetBrains but I do run into some issues that I thought maybe I\'ll ask here about.

1. It hangs unexpectedly and this happens often. O

Answer 1

In my case, the problem was a folder in the project directory containing 300k+ files totaling 11Gb. This was just a temporary folder with images results of some computation. After moving this folder out of the project structure, the slowness disappeared. I hope this can help someone, please check your project structure to see if there is anything that is not necessary.

Answer 2

I thought I had a speed issue with PyCharm but in the end it turned out that the output console in PyCharm does not necessarily emulate the output of state-of-the-art terminal applications.

Here's my solution: Click on drop down (arrow) symbol of your configuration -> click edit configuration -> click emulate terminal in output console -> click ok -> Run the configuration.

1. Change the inspection level

Current PyCharm versions allows you to change the type of static code analysis it performs, and also features a Power/CPU Saving feature (Click on the icon at the bottom right, next to the lock):

2. Change indexed directories
Exclude directories from being indexed which are set in the project paths but not actually required to be searched and indexed. Press ALT+CTRL+S and search for project.

3. Do memory sweeps
There is another interesting feature:

Go into the settings (File/Settings) and search for memory. In IDE Settings>Appearance -> tick Show memory indicator. A memory bar will be shown at the bottom right corner (see the picture below). Click this bar to run a garbage collection / memory sweep.
