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

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.
