Comment 1 Tomas Hurka 2009-10-16 13:54:18 UTC 
I am unable to reproduce it. I used after cold startup with existing userdir. See the log below:

Product Version: NetBeans IDE Dev (Build 200910151401)
Java: 1.7.0-ea; Java HotSpot(TM) Client VM 16.0-b06
System: Windows XP version 5.1 running on x86; Cp1252; en_US (nb)
Userdir: C:\Documents and Settings\Administrator\.netbeans\dev

@5941 - ModuleInstall for org.netbeans.modules.profiler.selector.spi/1 called dT=0
@5942 - ModuleInstall for org.netbeans.modules.profiler.selector.ui/1 called dT=1
@6166 - ModuleInstall for org.netbeans.modules.profiler/1 called dT=224
@6166 - ModuleInstall for org.netbeans.modules.profiler.j2ee.sunas/1 called dT=0
@6166 - ModuleInstall for org.netbeans.libs.cglib/1 called dT=0

I will try different machine.
Comment 2 Jaroslav Tulach 2009-10-16 15:49:26 UTC 
Can't you eliminate all work done in org.netbeans.modules.profiler/1? If the ModuleInstall is empty, then it does not 
matter how bad configuration of a computer is used to execute it.
Comment 3 Tomas Hurka 2009-11-11 05:37:13 UTC 
I removed profiler initialization from restore() method. I would still like to know how you have got 23 seconds long initialization with the original code.
