Description Mik Kersten CLA 2009-07-28 19:38:38 EDT 
Minimizing task editor open is a theme we've had since the start of Mylyn, and thanks to offline storage and other improvements, we've got it working quite fast in most cases.  I think that in order to minimize the friction of working task-focused, we should make it instant.  We can use the ~200ms average reaction time threshold as feeling "instant".

	"Mean RT for young adults is approximately 215 milliseconds to a detect visual stimulus, and approximately 160 milliseconds to detect an auditory stimulus."

Bug 284154 is related, since our bottlenecks are likely to come from forms and text viewer rendering.  But before addressing any particular bottlenecks we should profile.

I'll write a performance test for meassuring open time.

Comment 5 Steffen Pingel CLA 2009-10-07 14:44:01 EDT 
The performance tests which include opening a stack trace in a task editor do not show any serious performance regressions in 3.3 compared to 3.2.

Shawn, can you check these changes? The planning part was always created regardless of the expansion state of the section.

These look sane to me.
