36629 - New file-picker slow ("open/open file" tree-widget)

Status: VERIFIED INVALID

(Core :: XUL, defect, P3)

Description

[R.K.Aa.]

Build 2000-042009-M16 Linux on a P120

With the new filepicker widget, ittakes very long to do anything.
From i click on "File Open" till the filepicker actually appears takes 11
seconds. To change directory to a dir with 309 files takes 24 seconds.

These operations together used to take about one second with the "old" design
used in nb1b, about the same it takes with NC4.7.

Yes, I know the tree widget is slow.  I have plenty of bugs on this already.

Actually, something was badly broken in launching the file widget on linux 
for the verification builds this morning (but I don't know what). This was 
taking ~30 seconds to pop up, even on a fast linux box. 

I see though that performance in a current debug build is ~2-3 secs., about 
the same as yesterdays verification build performance. 

I'll just verify this as is, but will check perf tomorrow. CC: pavlov in case
this changes his life in some way.
