Excessive CPU, Memory, and Energy Use When Salesforce Extension Pack is Enabled

[jeramy-dichiera]

Summary

When the Salesforce Extension Pack is enabled I am experiencing greatly increased CPU, memory, and energy use. Currently Visual Studio Code 'Code Helper' is using 214% CPU, 303 energy impact, and 1.86 GB memory.

Please let me know if there is any specific information I can supply.

Steps To Reproduce:

1. Open a code base in Visual Studio Code with Salesforce Extension Pack enabled.
2. Open Activity Monitor

• Note that Visual Studio Code Code Helper is using excessive resources.

Expected result

When using the Salesforce Extension Pack, Visual Studio Code consumes less resources and can be used on battery power.

Actual result

When using the Visual Studio Code Extension Pack, Visual Studio Code appears to use excessive resources and needs to be disabled in order to retain battery life.

Additional information

Feel free to attach a screenshot.

I am also experiencing this issue. VS Code with the Salesforce Extension Pack enabled is rendering my laptop useless as it is so bogged down at 100% CPU Usage.
Version: 1.37.1 (user setup)
Commit: f06011ac164ae4dc8e753a3fe7f9549844d15e35

My CPU usage goes down drastically if I disable the SF extensions. Please let me know if I can provide additional detail to help resolve this issue.

This happens for me only when Indexing of Lightning Components occurs by Aura Component Extension. Only then my CPU utilization is 100% and PC is useless. It seems this indexing is a CPU hog.

I also seem to be caught in the endless Indexing Lightning Components cycle. What information would be helpful fro me to provide? Thanks

Here is a sample of the error output I get:

I also got @rapsacnz 's error but no excessive CPU usage issue.

I do have other issues like no longer able to retrieve/deploy from/to target org (when right click Manifest folder -> Package.xml).

See more info here : #1840

[pogilvie]

Me too. I've had the spinning 'Indexing Lightning Compoents' issue. I disabled the Aura component extension and it stoped. BTW I'm on OSX with all updates installed.

[ralphcallaway]

Ditto, I can hardly type vs code gets so slow with the Aura component extension on.
