Extension loads slower in dev version (when compared to current release version)

#1238 Check if there have been no performance regressions)

Based on initial analysis, the extension takes twice as long to load (without enabling the analysis engine).

MacBook, tested loading of extension 5 times.

• Load times of current (release) version of extension:

  • ~550ms to load all npm packages
  • ~650ms to automatically set the interpreter
  • ~660ms to completely load and activate the extension (sometimes as low as 500ms)

• Load times of current (dev) version of extension:

  • ~1,412ms to load all npm packages
  • ~1572ms to automatically set the interpreter
  • ~1588ms to completely load and activate the extension

• With PR Performance improvements to load times of extension #931 I was able to get extension load times to around 200ms.
• We've regressed from the improved 200ms to 500ms in the current release to more in dev version.

So one of our npm dependencies has gotten slow to load?

Doesn't look like it, looks more like our code.
Haven't had the chance to look into this.

This is no longer an issue.
