Steps to reproduce

Intellisense is slow both in template and in script parts of Vue files. I've had a look at the output, and it seems a bunch of the requests are taking a long (multiple seconds) time.

The only thing I'm doing in this test is writing <div, expecting the tag to be closed automatically, and waiting. I see similar results, of requests taking a long time when editing the script part, or anything else essentially.

What is expected?

Intellisense is completing within a reasonable time (100ms?), both when editing template and script

What is actually happening?

Intellisense is extremely slow, often taking 10s of seconds before completions are available

Could you install a VSCode extension called Volar Labs to check the memory usage?

  • Turn off Hybrid Mode
  • Open a .vue file
  • Click Vue / TS Memory Treemap in the extensions tab

It spits out an HTML file, is there an easy way to share that?
