[JetBrains IDE/JavaScript] Horrible performance issues when using the plugin

[NorteX-dev]

• OS version: Windows 10 (10.0.18362.959)
• Editor: JetBrains WebStorm, same family as IntelliJ
• Editor version: 2020.1.3
• Programming language JS (both Node and classic), HTML (+ CSS), EJS
• TabNine extension version: 0.1.1

Issue Details: The plugin gives terrible performance issues with the IDE. Every 5-ish words, the IDE goes "No Response". It also hangs a lot of the times when typing, effectively slowing me down instead of speeding me up. Without the plugin, the WebStorm process uses about 0% - 1% of the CPU usage, while WITH the plugin installed, 40% - 50% making the whole CPU work on 100%. Because of that, I had to uninstall the extension until I can find a solution to this problem, as this makes the IDE unusable.

hi @NorteX-dev,

Thanks for reaching out, In order to investigate this, we could use additional info: Does the CPU level still raising when you're not typing? or does it level down? Do you mind sharing your IDE logs, for us to investigate? What CPU do you have on your machine? What RAM?

Can you try and disable the local deep learning model, and see if this changes CPU consumption? (you can enter the config by typing TabNine::config , and then uncheck the checkbox at Deep TabNine Local -> Enable TabNine Local)

Thanks!

Hi @NorteX-dev - does your project have a .gitignore file? And all the relevant folders are excluded (module_module, bower, etc.)?

[NorteX-dev]

First off, thanks for both responses and sorry for my long response times. @yanir-codota After further investigating, I found out that the CPU level raises only when I'm typing and immediately relaxes when I'm not typing. I'm using an i5-6400 with DDR4 16 GB memory. I see no other problems anywhere with this setup (especially when coding), so I suppose the specs can't be a problem. I couldn't find the exact setting for deep learning, but I assume it's this: I have disabled it, and yet, nothing changed, except the TabNine suggestions didn't appear anymore (so I had high CPU usage + no suggestions anymore) These are the logs as wanted. There are some errors and things, and a bunch of spam from other extensions... idea.log @dimacodota Yes, I do, and it contains the node_modules folder. So I don't think TabNine should be still indexing these.

Edit: I'm going to use the extension when I'm coding now, so I can get more information on the topic.

hi @NorteX-dev , Thanks for the logs, and all your inputs,

The TabNine plugin is spawning a subprocess in the name of 'TabNine.exe'.
Just to make sure we follow the right path here, Can try and figure out which of the processes is raising the CPU consumption when you experience this issue (the TabNine subprocess or the webStorm process itself)?

Thanks!

[NorteX-dev]

WebStorm process itself, but only with TabNine installed. It's not as intense now as back when I created the issue but it's still obvious and obnoxious.

@NorteX-dev, can you please send us your configuration file? type TabNine::cfg in your editor to locate it. Thanks

@dimacodota I have the same issue as NorteX-dev on 10 Aug 2020. Unnamed process with Webstorm icon uses 6-8% of CPU.

If I disable TabNine plugin, it still use CPU. If I kill WD-TabNine.exe and both of TabNine.exe processes it still use CPU until Webstorm restarted.
