WebStorm 2024 got very laggy?

Thank you for creating a support ticket, this would help us to investigate the issue.

As initial step, I'd suggest reducing the `Xmx` value at Help | Change Memory Settings to 6Gb at most, as basically the JVM takes the entire heap size (Xmx), it doesn't run the garbage collector aggressively before the heap size limit is reached. This can cause high RAM usage and overall IDE slowdown.

Same here on WebStorm 2024.1.5. MacBook Pro M1 Max.  Cannot even take a memory snapshot, it just freezes. 

Thanks Elena Pogorelova! I switched to 2024.2 EAP and brought down the memory settings to `6Gb`. That seems to have helped a bit!

I Sam, I have the same problem

rubymine 2024 on windows with WSL2 has been continuously unresponsive for me since updating to 2024. Every 5-20 minutes i need to restart the IDE because it no longer will let me type any text, search, open specific files, commit, etc. 

Adnan could you please specify whether you've tried 2024.2 Beta as well? How does it go there in terms of performance? If the problem persists, it'd be great if you could provide more details with the whole logs' folder (Help - Collect Logs..) on our tracker. 

I'm experiencing significant performance issues with WebStorm, and to a lesser extent, with PHPStorm and CLion. The problems are particularly severe with WebStorm:

1. Switching from Chrome to WebStorm causes the IDE to freeze for approximately 10 seconds before becoming responsive again.
2. After extended coding sessions (10+ hours), a complete restart of the application is necessary to restore functionality.
3. The integrated terminal feature has become unusable due to these issues, forcing me to rely on external terminal applications.

It's worth noting that these problems are not due to insufficient hardware resources. I'm using a high-performance XMG Neo 17 (2024 model) with upgraded specifications, which easily handles resource-intensive tasks.

As a user of the All Products Pack, working across multiple technologies, these performance issues are significantly impacting my productivity and workflow.

Has anyone else encountered similar problems or found potential solutions? Any assistance or insights from the JetBrains team would be greatly appreciated.

Thank you for your attention to this matter.

Horvat Goran360 do you have any tools watching the project files are re-building the application on Save? If yes, does excluding the build target folders from project (Mark directory as/Excluded) to get rid of re-indexing when flashing the generated stuff to disk make things any better?
Delays on changing focus are usually caused by synchronizing IDE virtual file system with external changes (that happens on moving focus to the IDE frame) and re-indexing newly added files. You can turn this synchronization off in Preferences | Appearance & Behavior | System Settings, Synchronize external changes when switching to the IDE window or opening an editor tab

Hello Elena. I didnt even think about this. Those are some good points. Yes we have an automatic build and sync happening on our side. I will try the solutions above. As well cache clearing. Ill keep you updated have a big coding session today so ill see if above did the trick or not atleast for the WebStorm on PHPStorm and CLion we do not have the build process well not like on WebStorm anyway. 

Same here this is getting nuts. I have no such issues whatsoever in Rider etc and there i got some pretty massive backend systems running! Disabling copilot etc code line completions doesnt help. 

what i have noticed though is that after a clean start it sort of is ok for me for about 2-3 hours depending on how much i do. usually i start to notice once i start to work on more than 6 files and its been 1+ hours of coding. 

Really annoying issue guys… I am thinking maybe RAM related and caching?

Also i am running webstorm with 6192m for VM options

It's not just Macs. I have the same issue with both PyCharm and WebStorm on an Asus ROG 14 which is defo not an entry level machine. All plugins disabled, a relatively small project opened. Just pressing the right arrow to run the cursor is laggy.

I have started having this issue after upgrading to 2024.2.0.1 (242.20224.426) on macos Sonoma 14.6.1 (23G93), Macbook M2 Pro.

Edit: rolling back to my previous version (2024.1.5) fixed this for me.

If you're experiencing problems with the 2024.2.2 version and can't find any solution, I suggest you try these steps in order:

1. Disable Atom Material Icons (if you have it installed), restart, and test your app.
2. Increase your RAM to 6 GB, restart, and check again.
3. As a last resort, restore default IDE settings, then reinstall only the necessary plugins.

I performed all these steps in order, but you can try each step individually to see if it solves the problem.
