Reassign to editor team to evaluation.
Do not see C/C++ code in snapshot.

cnd code consume 1.5 second from 10.
IMHO slowness should be fixed in FindSupport.replaceAll() or FindDialogSupport.actionPerformed().

Comment 4 David Strupl 2011-06-09 12:59:45 UTC

There was something wrong with the virtual machine of the user. From the snapshot 36 invocations of

java.lang.Throwable.getStackTraceElement(int index)

took 4s which is really slow. Something was wrong with the java virtual machine of that particular user during that particular time.
