Steps To Reproduce

There isn't much needed to reproduce. When the extension is active in either a repo with NetSuite files or one completely devoid of NetSuite files when changing tabs/editors the system heavily lags for 5-8 seconds. The mouse buffers and slowly works its way through the path.

1. Open project with SuiteCloud extension installed
2. Open several editors
3. Switch between editors and wiggle mouse

Hi @df-pkennedy
Thanks for your message and all the info you shared with us.
I cannot replicate the issue with a project of similar size than yours. However, could you please share with us the following?

• A screenshot of your environment, I am specially interested in the info that appears in the status bar like in the follow image.
  

• Could you try to install version 1.3.2 of our VsCode Extension and see if you have similar problem? We have some suspicion about a feature that was inserted after.

Thanks.
