Description Marian Mirilovic 2006-12-04 20:58:17 UTC 
We are measuring significant regression on startup between builds :
200611281900-200611221900
on all platforms and both JDKS (1.5.0_09 vs. 6.0-b104)

Startup Time
1st usage 	24 % 	29 % 	16 % 	31 % 	28 % 	28 %
Subs. usage 	30 % 	35 % 	20 % 	37 % 	34 % 	36 %
Comment 1 Marian Mirilovic 2006-12-04 21:15:36 UTC 
Well, I found out the reason, it's because the status line is repainted every
100ms (see attachment).

I understand that showing text "Opening Main Window ..." and slow disappearing
is really nice and probably very important, the only one thing I don't
understand is why do we need to repaint the whole status line ? 

BTW: I can filter paint events from status line I guess - this will solve "the
regression" issue, but I would also like to know the answer of previous question
regarding repainting the whole Status line couple of times after opening the
main window.

Comment 3 _ rkubacki 2006-12-07 13:08:12 UTC 
StatusLine is subclass of JLabel so it is fine that this component gats repainted.

OK, either pass -J-Dorg.openide.awt.StatusDisplayer.DISPLAY_TIME=0 to tests or I
can udate it to turn this effect off if netbeans.full.hack=true. What do you prefer?
