Description ionuion 2012-11-26 02:12:40 UTC 
Users on the #netbeans IRC channel report severe performance problems when using the C/C++ plugin. 
Following two descriptions:

User 1 (fr**y):

Environment:
Product Version: NetBeans IDE 7.2.1 (Build 201210100934)
Java: 1.6.0_24; OpenJDK 64-Bit Server VM 20.0-b12
System: Linux version 3.6.6-1-ARCH running on amd64; ANSI_X3.4-1968; en_US (nb)
User directory: /home/a**w/.netbeans/7.2.1
Cache directory: /home/a*w/.cache/netbeans/7.2.1
GCC version: 4.7.2-2
4-cores Intel core i7 CPU

Behavior:
NetBeans IDE using 100% of all 8 CPU threads

In the logs:
WARNING [org.openide.awt.Toolbar]: Too long AWTTask: 11,890 ms for org.openide.awt.MenuBar$LazyMenu$MenuFolder@6000fb42(FolderList{MultiFileObject@71591b4d[Menu/Window]})



User 2 (l**r)

Environment:
NetBeans 7.2
C/C++ plugin, 
Java 7, 
64bit x86 
4gb ram

Behavior:
'after some time i use it the java process behind the ide starts to eat all the cpu'
'parsing a simple project requires 2 mins'

In the logs:
WARNING [org.netbeans.core.TimableEventQueue]: too much time in AWT thread org.netbeans.modules.sampler.InternalSampler@336ade6b

Please let me know what further information can aid in solving the problem.
Thank you.

First we need to check if it isnt something we fixed in 7.3 and limit number of parsing threads down to 4.
Sasha, please, investigate.
Comment 2 Alexander Simon 2012-11-26 07:41:32 UTC 
Please provide additional info. It can be:
- slowness report
- threads dump at the time when IDE eat 100% of 8 threads
- IDE profiling snap shot.

Thanks,
Alexander

Closing, as the users reporting the issues have not been present on the IRC channel, so the required artifacts cannot be provided.
