Hi @jonathanwiesel, we are doing different things to address the different performance issues with webpack being one of the tools being used but not limited to it. We are currently refactoring the extensions in order to cut down on our dependencies. We are also working on making some of those dependencies significantly smaller.

Some of the issues are related to the language servers and not the extensions themselves, so we are currently working on profiling them and testing new changes to make the code more efficient.

I am also experiencing this issue as of late. The two extensions that are mentioned in the performance notifications are the Apex extension and the Salesforce CLI Integration extension.

Hi @V1JAYENDRA - Can you attach the file noted in your original issue? We are investigating this and have work in progress (tracked under #2410). Some users experience these issues on some projects, so more information would certainly be helpful. The info here doesn't give us any more to go on. Information like the size of the project (number of files, number of objects, etc) as well as your machine specs would be helpful

Just experienced the same issue. I tried attaching the log here, but it's 30MB and github rejected it. I'm working on a new org - we have about 10 - 15 ApexClasses, and 4 ApexTriggers. Nothing else in the dx project.
I'm on Windows 10, running VSCode.

When I try to execute SFDX commands it is running for long time and no action is taken place. For example, if I execute sfdx: Authorize an org it is running for long time and no org is authorized.

Hi @hgolov and @pavithraMST - Thank you for providing additional information. When you experience the issue, is it all the time when you using the project? Or only when first opening it?

smaddox-sf on 15 Dec 2020

I only had it once and it was when I loaded the project/window.
Have a great day,
Hadassa Golovenshitz

Same issue. Takes a hell of lot of time to start and I need to start most times manually.

manjunathtj on 17 Dec 2020

Thank you all for the additional details. We have some changes in flight to reduce the size of the extensions and reduce dependencies between them. This should help the start-up scenario in particular. We'll keep you posted as we release changes so you can let us know if it's improved. CC @lcampos

(This also relates to open issue #2410.)

smaddox-sf on 17 Dec 2020

@smaddox-sf is there a timeline for those in-flight changes going live?

jamessimone on 12 Jan 2021

HI @jamessimone and all - We released some changes in Dec and have more going out weekly over the next couple months. After some profiling and analysis, we believe the main root cause is the core extension size and some of the dependencies between the extensions. It's not quick to unravel some of this, but we are making progress. We'll post major updates here so you let us know if things are improving. Thanks to all who have shared data & details - extremely helpful!

@smaddox-sf thanks so much for the follow up. I appreciate it!

I'm also having the same issue. My computer becomes unresponsive as a result.

This is still happening. I tried Sun JRE and Azul JRE on both the same issue. High CPU load for very long time.
For me it is happening on two computers with the same large project open. Always after opening VSCode with that project.

PawelWozniak on 2 Feb 2021

@smaddox-sf just for curiosity, is the speed increased been worked up using the Webpack extension bundling presented in VSCode v1.32?

jonathanwiesel on 2 Feb 2021

Some of the issues are related to the language servers and not the extensions themselves, so we are currently working on profiling them and testing new changes to make the code more efficient.

Thank you for the detailed insight @lcampos, I can only feel excited about what is to come, seems like big changes that will make a lot of lives easier 😀

jonathanwiesel on 2 Feb 2021

I probably face the same issue. Is there any work-around? Thanks.

cywang16 on 18 Feb 2021

also having problems with this on a new computer and trying to launch vs code for a large project. it seems like it's not just the apex extension, though. if i disable the whole extension pack and enable only the CLI integration, it still takes a really long time to load and uses a lot of CPU. sometimes it eventually loads (after maybe 50-60 seconds), but sometimes it doesn't.

i can't get a CPU profile because the "save extension host profile" button never becomes enabled/clickable.

ajw725 on 5 Mar 2021

Hi @ajw725 - Thanks for trying on the CPU profile and for all the project details on #3024. We've been working through changes that are helping with _some_ performance issues. We're next profiling the language servers to find the bottlenecks with large projects to find other improvements we can make.
