This extension adds a noticeable delay when starting gnome-shell

[terencode]

My gnome-shell with all extension except this one enabled starts in about 4 seconds with 17 extensions enabled.
Adding yours makes it up to 20 seconds, the equivalent of having 85 extensions enabled.

What could cause such a difference?

Have you been using it for a while, or just installed it?

I've been using it for a while.

Maybe your cache file is very large.
In the settings page - what are the values for:

1. History Size
2. Max cache file size

Also - when did you update the extension last time? Could it be that it's a very old version?

[terencode]

I'm using the latest version from the gnome-shell extension website.

1. History Size: 50
2. Max cache file size 1024
