Description gofeidao 2011-08-19 19:18:18 UTC 
Product Version = NetBeans IDE 7.0.1 (Build 201107282000)
Operating System = Windows 7 version 6.1 running on x86
Java; VM; Vendor = 1.6.0_26
Runtime = Java HotSpot(TM) Client VM 20.1-b02

It work very slow when using JDK 64 bit version, memery costs may temporary raise up to 1.3G. When I swtich back to x86 version, everything go fine.

Could you please specify what action is causing the IDE to be slow, use more memory (what did you do)? Thanks in advance.
Comment 2 Tomas Mysik 2011-08-22 13:44:53 UTC 
Is it reproducible with JDK update 24?

Very likely duplicate of issue #195278 (problems in JDK update 26). To confirm, it would really help us if you could attach a profiler snapshot [1] taken during the slowness. Just reopen this issue and attach a snapshot (snapshot of one or two minutes should be fine).

Thanks for reporting.

Created attachment 110145 [details]
the snapshot 

Thank you for your reply.
I took a snapshot of this issue.
And here are my netbeans startup options:
================================
netbeans_default_options="-J-client -J-Xss2m -J-Xms32m -J-XX:PermSize=32m -Xms512m -J-XX:MaxPermSize=384m -Xmx1024m -J-Dapple.laf.useScreenMenuBar=true -J-Dapple.awt.graphics.UseQuartz=true -J-Dsun.java2d.noddraw=true -Dawt.useSystemAAFontSettings=lcd -J-Dfile.encoding=UTF-8"
=====
It occurs when I just open the IDE and type some code into the editor, the first character may takes 10 more seconds to show up, while the hole IDE stuck in "no response". However it never occurs with JDK x86 version.
Comment 4 Tomas Mysik 2011-08-23 08:59:33 UTC 
Weird, nothing suspicious in the attached snapshot. When exactly have you created it? The best is to:
- start IDE
- start profiling
- type a character
- (wait a couple of seconds)
- stop profiling

Maybe, it could be helpful for us if you could attach a normal thread dump [1]:
- start IDE
- type a character
- take thread dump (or two)

Just reopen this issue.

Thanks for your cooperation.
