Hi,
my tree viewer shows a relatively plain model (2000 elements in the same
node). When I use a ViewerSorter, the Display thread is blocked for
about 20s (!) before showing the sorted tree. Profiling does not reveal
anything special, most of the time is spent in some SWT internal stuff.
When I sort the elements in the IContentProvider instead, sorting time
drops below 3s. Still a lot but I can live with that.
Am I missing something?
Regards
Jan

As sorting is usually triggered on/off, I set the viewer after setting
the input. In the meantime, I moved sorting into the content provider
which fits my needs.
Thanks for your help
