Hi, I am the lead developer of Audacious (a GTK+ based music player). Lately I have been trying to improve the performance with large playlists (i.e. on the order of 100,000 entries). The one remaining problem spot seems to be GtkTreeView. I am attaching a simple test program that creates a GtkTreeView with 3 columns and 100,000 rows. With GTK+ 3.2.2, the program uses 29 seconds of CPU time before reaching idle, on a 2 GHz Core 2 Duo. (GTK+ 2.24.8 is considerably better, at 10 seconds, but still too slow for practical use.) Is there any way that GtkTreeView can be made usable for such long lists?
