Build: NetBeans IDE 7.0 Beta (Build 201011152355)

User Comments:
matusdekanek: running a web project or profiling it (tomcat) somehow causes IDE to heavily utilize processor. Any action then causes slowness.

matusdekanek: stopping profiling session

massimo: Was opening a Matisse JPanel at startup

GUEST: Searching for external changes...



Maximum slowness yet reported was 29141 ms, average is 16833

Comment 5 Jaroslav Tulach 2011-01-08 16:01:06 UTC 
org.openide.loaders.DataObjectPool.getTargets() takes a lock, blocks a recognition and calls into File.listFiles().

The report from Nov 19, is the most important one.
