Performance issues when editing/pasting

[ITModernisation]

Type of JetBrains IDE (IntelliJ, PyCharm, etc.) and version

IntelliJ IDEA 2024.3.2.2 (build IU-243.23654.189)

Operating System

Linux 6.8.0-52-generic (amd64)

TeXiFy IDEA version

0.10.0

Description

We are running a large tex project, containing about 20 main documents, each composed of numerous sub-odinate tex files, with many listings, images and so forth.

1. the good news first: your plugin is fabulous! It is a perfect assistant for my daily work, which is designing and maintaining our products using LaTex with lots of packages and self developed macros.
2. problem #1 is the fact that soon after starting my intelliJ/tex project, my machine starts humming like it does when it is indexing. But: it never stops doing it. The machine keeps humming without interruption, even if I don't touch the keyboard. This decreases performance significantly. At times intelliJ informs me that your plugin decreases performance and asks if I want to disable it.
3. problem # 2 is the fact that an EDIT-PASTE into a tex file leads to a total disruption of my work. Nothing goes, the intelliJ workbench is halted for a minute or so. This happems also when I am inserting a new-line charcter. When I PASTE being in the COLUMN MODE this does NOT happen! But it is very awkward to constantly switch between the two editing modes.

If you need any further information please let me know or call me.

Thanks a lot in advance

Hi, thanks for reaching out. How many files and lines of code are we talking about? You can see this for example with the statistic plugin if you add tex as an extension.
I cannot reproduce any performance issues with a project with 250 LaTeX files with total 12k lines.

If you could create a profiling snapshot as described in
https://hannah-sten.github.io/TeXiFy-IDEA/troubleshooting.html#debugging-performance-issues
then that should directly pinpoint the source of the performance issues.

I'm not quite sure if the high CPU usage and the UI freeze are the same problem, so separate snapshots would be helpful.
(The exception is unrelated)

[ITModernisation]

This is the file statistics covering the total tex project.
More will follow ...

@ITModernisation As found in #3893, some of this could be caused by the "package not installed" inspection, please try disabling it

[ITModernisation]

This is not a "package inspection" or caching or something else inspection. Anyway, we can not work with this, so we decided to uninstall your plugin.

Alright, I will close this issue then. If you ever have more information to help me reproduce and fix the issue, please reopen and I will look into it.
