Copilot in intellij uses an absurd amount of memory

Body

Hi folks, I have been enjoying quite a lot the plugin so far, it really helps in doing a lot of the mundane repetitive work that once one would need to do.
However I noticed a massive degradation of performance of my system (Mac OS Monterey), and that Intellij was using close to 10Gb of memory.
Not only that, but due the plugin very intensive cpu request, Intellij alone was consuming 10x more energy than the rest of all the applications on the system combined :(
I'm running version 1.4.6.4092 of the plugin on intellij Build #IU-233.13135.103,

I looked into an hprof dump and found that there 67% of the largest offenders in memory usage came from a single class:
CopilotTextInputTextArea

Maybe there's a way to improve all that?

Thanks

Yeah big time, i've got an almost maxed out MacBook Pro and it CHUGS whenever the pane with Copilot chat is open but closing the pane completely resolves the performance issue. Kind of annoying to have to remember to close the pane so often. The plugin isn't open source either so we can't open a PR to fix :sad:

@slavkobojanic I have the exact same behaviour. As soon i open up Githup Copilot chat the CPU goes up and as soon I close the chat, the CPU is normal again. This behaviour is since Intellij 2024.2. Bevor I didn't had this behaviour. Really odd.

The IntelliJ Copilot plugin is consuming excessive memory and severely impacting my IntelliJ performance.

Seems to be another relevant thread:

On my docker image the versions are as follows.
Copilot plugin version:

1.5.29.7524

And based on the page:

Looks as if am using the greatest and latest.

Note: The intelliJ community forums are also updated on this fact.

Is anyone looking into the copilot plugin for linux/docker?

I had a dreadful experience using it on my development Docker machine. At one point, I received a warning from Intel about my SSD being at risk. My Docker memory settings were insufficient for the plugin’s needs, causing my computer to struggle significantly.

I believe this issue is specific to Linux, as the plugin works fine on my Windows IntelliJ setup.

For the record, my windows plugin version is:

1.5.29.7524

Running on IntelliJ:

IntelliJ IDEA 2024.1.7 (Ultimate Edition)
Build #IU-241.19416.15, built on October 16, 2024

Licensed to KUKA Roboter GmbH


Runtime version: 17.0.12+1-b1207.37 amd64
VM: OpenJDK 64-Bit Server VM by JetBrains s.r.o.

I see my windows IntelliJ consuming 3 GB of RAM right now. Pretty soft.
