Ethereal built with gtk+ 2.2 is still much slower than with gtk+ 1.2
I think there are two problems :
- rendering performance (probably pango related) : it can have a strong
impact when opening big capture files ;
- threads : the use of threads in our gtk2 version also has an impact on
performance (glib/gtk probably uses mutex when threads are enabled
which explains the slowdown).
I'm not sure we really need threads to update tap listeners : the
mecanism used with gtk+ 1.2 (gtk_timeout_add) seems to work well enough.
At least, we could provide a configure option to disable threads.
When opening a file containg 182465 frames with the following filter
"frame.number == 200000" so that nothing is displayed (to avoid text
rendering in the GtkCList), I get the following performances :
- 2'46 for the gtk+ 2.2 version with threads ;
- 2'05 for the gtk+ 2.2 version without threads.
