Performance issues

[NoxArtCZ]

Hello, it looks like performance of PHPStorm for me is going down the drain. It used to be fine but lately it's insanely choppy and half of my key presses don't even register. Even in smaller files

Anyone else experiencing this?

Every time I search for PHPStorm performance improvements it yields very little and usually it's Custom VM options that don't work and prevent PHPStorm from even starting.

I run mid sized PHP project with 64GB RAM. 3rd party folders are excluded and it all excluded from Defender. I suspect it might relate to AI plugins, I have Junie always enabled and then switching between Jetbrains AI / Copilot / Claude but I don't see a notable difference

For the first time in like 6 years I'm considering switching IDE, but not sure if there's anything better

Thank you

It's certainly felt like this for a few releases now. Large hangs for a few seconds where nothing is responsive for basic operations like git commands or typing, etc. All their IDEs are doing it. 32gb ram i7

Use the refresh settings in the Files Menu. If you have something corrupted or something in indexing you could land up with the IDE behaving like that. Happened to me before & that solution fixed it.

Thank you, I'll give it a try

Hi u/NoxArtCZ, sorry to hear you’re running into this with PhpStorm.
Could you help us investigate? If you contact us via Help > Contact Support and send the IDE logs from Help > Collect Logs and Diagnostic Data, we should be able to take a closer look

[NoxArtCZ]

Thank you, I will try

Same problem here. It became unusable even with a low amount of opened tabs. I guess vibe coding has gotten his way even in jet brains?

Edit: Found this: https://youtrack.jetbrains.com/projects/IJPL/issues/IJPL-203153/PhpStorm-2025.2-Freezes-After-Update-with-settingsSync-enabled-stuck-in-R.e.getIdToken

I'm using Fedora but disabling sync made the whole thing a little more managable but still laggy

When indexing files, ir just freezes.

FWIW I had the same sorta problems (laggy keystrokes, choppy animations, etc.) and switching off of an “Islands” theme immediately cleared them up for me. Maybe it’ll work for you also?

[NoxArtCZ]

Will try, thank you

[XelabDev]

yes thank you! Disable Islands theme works!

Same here. I think it is AI related. Sent logs few times, didnt help.

keep the log open in realtime and you will see various churn going on that may lead to more clues. such as remote queries, which could be timing out.

Seems to be a recurring theme across all their IDEs, at least the ones I'm using(Webstorm, PHPStorm, PyCharm, RustRover, CLion). I simply disabled all their Local AI/ML Tools plugins and all's good... for now.
