[ricardoboss]

To Reproduce Steps to reproduce the behavior:

Hi @ricardoboss thanks for reporting.

Are you sure is the AZD plugin? When you remove it the rider is working faster?

Any chance you attach a thread dump of rider with the plugin installed?

Thanks 🙏🏻

[ricardoboss]

Hi, yeah it's definitely azd. I found out by disabling them one by one.

I created this backend thread dump: 2024-02-16_21-33-56.532.tdump.zip

Let me know if you need more dumps.

[ricardoboss]

This might also help: a thread dump with only azd and the required plugins enabled: 2024-02-16_21-40-35.158.tdump.zip

[Jonatha1983]

Hi, I checked both zip files and couldn't find the point from where to start the investigation.

I opened my Rider project ( almost empty just for the plugin's purpose) and could navigate between the plugin and the editor with no memory consumption.

If you can, please provide me more details or take a thread dump when the Rider starts its high mem consumption.

I will keep trying to reproduce in any case.

[ricardoboss]

I have activated the memory indicator and as soon as I open a project, it shoots up to the memory limit. That is, unless I deactivate azd 🤷

I noticed this problem only on mac. On Windows, everything is fine. Might that be the problem?

[Jonatha1983]

I am using a Mac M2 so I guess not related.

Is it the same repo?

If it is as soon as you open the Rider it is related to the detection of the repo I guess. I ll try to look in that area.

[Jonatha1983]

@ricardoboss Is your repo a multi module repo? Bare repo?

Any chance you have another repo to test if it is a global issue or something specific to that repo (with rider) ?

[ricardoboss]

It's not specific for the project. It happens with any project

[Jonatha1983]

Hi @ricardoboss

Sorry for the huge delay, but I had some other tasks including a huge refactoring for the upcoming IDE release.

Are you still facing this issue?

If yes does your organization contains a large number of repositories? Or users? If possible try to provide me some more details that can give me a good starting point to investigate.

Thanks and again sorry about the delay.

[ricardoboss]

Hi and thanks for taking the time. I have been using the EAP version of Rider for the last few weeks and haven't had any performance issues while using azd. Even after switching back to the stable version. Maybe it was a Rider bug then? idk... in any case, I will monitor performance in the upcoming IDE and plugin versions. I consider this issue closed as of now
