It looks like newGeneratedSources and insertSourceActors can have a significant performance impact. This comes up for instance when previewing a token, which does an evaluate under the hood and creates a new script.

STR:

  1. start launchpad and open localhost:8000
  2. in the controlled tab to go todomvc
  3. pause in the launchpad and hover on some variables.

This will be a big enough app where new sources are somewhat slow (250ms)
