I don't recommend this if you are developing a graphical interactive program. Most python programs are essentially "batch" programs, and you probably won't notice the extra time it takes to run. Switching to Above Normal priority gives P圜harm something closer to the empty core that it was probably tested on.Īs for Below Normal on python.exe, basically you don't want to slow your computer down with your own development. Whenever the sum of all programs > 100% on a core, you see lag. But now you open Chrome and 30 tabs, Fiddler, an FTP program, iTunes, Word, Slack, etc, and they all compete with P圜harm at the same CPU priority level. They have probably at least ensured it can run without lag on an empty core. Think about it: Yes P圜harm requires a lot of CPU, but the P圜harm developers aren't stupid. Then right click again -> Process -> and select "Save for pycharm64.exe" and similarly for python "Save for python.exe." Finally in Process Hacker go to Options and select "Start when I log on." This will make it so that ALL Pycharm and python executables acquire these CPU priorities, even after restarting the program and/or Windows, and no matter how many python instances you launch.īasically, much of the P圜harm's lag may be due to conflict with other programs.
I used Process Hacker: Right click on the process -> Priority -> Set the priority. You can do this manually, but I recommend using a program which will preserve the setting across restarts and for multiple instances. Set the CPU priority for Python processes to Below Normal.Set P圜harm's CPU priority to Above Normal.What worked beautifully, almost perfectly: I also tried playing around with CPU affinities for the process, which briefly worked but not really. Turning off inspections didn't help at all, and I didn't have any special plugins that I recall. P圜harm takes less than 1GB of RAM for me, so that wasn't the issue. Solutions that didn't work: I have 16GB of RAM and was still having horrible lag. I found a solution to this problem that works beautifully on Windows, and wanted to share it. I have also contacted JetBrains regarding these issues, but honestly I tend to find nice solutions to common problems here and I thought I might as well ask Now look, I understand that diagnosing things like these is difficult without any sort of snapshot or more information about what is going on, but I am simply asking if anyone has ran into these issues before and if so, how did these get resolved?

Mac OSX Lion running on MacBook Pro (mid 2010) with 8GB RAM The only way I am able to fix (2) is by going to P圜harm -> Preferences -> Python Interpreters -> Paths -> Reload List of Paths but I have to do this often enough to warrant asking about a more permanent fix. as well as some of the modules I import such as sys (these are the most common offenders :) ). Often when I open a project P圜harm seems to flag all the built-ins as Unresolved Reference warnings.

Overall, its a little bit slow for my taste and I would love some tips on how to increase the performance of the IDE
