Description Marian Mirilovic 2009-07-31 11:16:02 UTC

Tried build NB Dev (20090731), JDK6u15 32b, Ubuntu 9.04 64b (Core2Duo 2.5GHz 4GB)

Steps to reproduce:
- run IDE (for logging use -J-Dorg.netbeans.log.startup=log)
- install EB & set EB as Web Browser
- open some web project
- deploy index.html
- run index.html (stays opened in Web Browser)
for 1 :
-> restart IDE - restart took ~25s (Window system loaded dT=17049)
for 2:
- close Web Browser
-> restart IDE - restart took ~11s (Window system loaded dT=860)

-> P2, TM=6.8

Comment 4 Stanislav Aubrecht 2009-07-31 14:19:07 UTC

does the info above mean there's no regression when browser window is closed at shutdown?
if so then i can postpone browser initialization until the browser window is activated

Comment 5 Marian Mirilovic 2009-07-31 14:27:47 UTC

P1 - >100% perf. regression on startup ... 
Standa, would be really nice to have this fixed for M1 if possible (clone will be done tomorrow later in the evening)

> does the info above mean there's no regression when browser window is closed at shutdown?
definitely

Comment 6 Stanislav Aubrecht 2009-07-31 16:27:39 UTC

hotfix: core-main fb752d78e631
please revert if there are any unwanted side-effects

leaving opened as P3 until a proper fix is available after 6.8 M1 release
