I have been testing with the problem in my previous post,  *reset_rc_styles_recurse *being very slow.

I made a small test case that adds 201.000 items to the view.  Thousand items with one header item.

When I detach gtk_container_remove(), then gtk_container_add() again, it the add takes:

• clearlooks: 9.3 seconds
• aurora: 9.2 seconds
• ambiance: 15.5 seconds
• cleanice: 3.97 second
• Dust: 10.6 second.
• industrial: 6.85 seconds.
• Luch: 5.0 seconds.
• Mist: 4.3 seconds.
• Murrine Candy: 4.5 seconds.

The difference a factor 4.  That is kinda huge.  Now this is a pretty big difference,  but 4 seconds is still to slow for normal use.

But I use it on small views, and even there the impact is big and significant..   0.5 seconds or 0.12 second?
