An extension I'm working on is having severe performance issues, causing the screen or gnome to freeze and other issues.

I'd like to fix it, but I have no idea how or where to start. Is there a way to monitor and profile shell extensions? If not, what is a good way to approach this problem? Will I have to disable features until the lag stops? Or will I have to do the profiling by logging a lot of timestamps?

  • Don't you get any error messages in LookingGlass ?

  • Nope, nothing. Everything works (kind of) fine

  • Well, if there's nothing useful in the journal either then the only thing that comes to mind is gdb. If that fails to produce anything useful then you'll prolly have to remove features/modules from your extension to isolate the problem.
