I’ve recently upgraded Mavericks (OSX) to 10.9.2 and discovered that Sublime was performing terribly slow. I’m talking 1 second (plus) delays in keyboard stroke to render in the editor.

Solution

My first test was simply wipe everything out from ~/Library/Application Support/Sublime Text 3. Success, Sublime is back to its former glory. But I still want all my sweet settings and plugins…

Remove everything EXCEPT Installed Packages and Packages. For me that meant deleting:

  • Backup
  • Cache
  • Index
  • Local

You may have to enter your license again but that’s nothing major.
