This Bugzilla instance is a read-only archive of historic NetBeans bug reports. To report a bug in NetBeans please follow the project's instructions for reporting issues.
I select a file in my project, time how long it takes until the file populates inside of the editor, and then time it again to see how long it takes for the code to be parsed (how long before you can highlight variables for example). To get a 160 line file into the editor took 5 seconds. For that same file to be parsed took an additional 15 seconds for a total of 20 seconds before you could do much with it. I tried the same thing with the same file in eclipse. The total time was less than a second. Note that this file is located on the network...but then again it is for eclipse too and that has no problem with it.
Note that this is similar to 120222...not a duplicate, but it may have the same root cause and this is much more detrimental to productivity than the other defect.
Note that this issue seems to get worse if you select another file before the first one has finished populating. I've been "hung" for several minutes now with Netbeans unresponsive.
Thanks for the measurements. When waiting could you please take several thread dumps to see what the IDE is doing - http://wiki.netbeans.org/wiki/view/GenerateThreadDump? Thanks

Added three dumps. Note, I really think this should be a P2. It's very difficult to do much when things are this slow.
Thanks for the thread dumps. There are some performance tips on nb.org and wiki, please read through them to see if something applies to your situation: http://performance.netbeans.org/howto/jvmswitches/index.html http://wiki.netbeans.org/wiki/view/NetBeansUserFAQ#section-NetBeansUserFAQ-Performance This is likely to need some time for analysis and I'm not sure how far we will get with it. Maybe java-infra gurus will have some insight too...
Any update? I think 6.2 is supposed to address performance issues correct?
No, no update so far, sorry. Yes, 6.1 is mostly bugfixing realease.
Just checking in...any update on this? 6.1 is final now and it seems to have everything in it you could want and appears to be fairly stable. The performance however with larger projects across the network is atrocious at the current time.
Hi, I don't have much update except for the issue #129561, which we fixed __after__ the final build of 6.1. The fix, however, should be available in 6.1 patch1 (when this is available). I'm not sure how much effect the fix will have in your particular usecase, but in general the fix will decrease the number of redraws and speed up processing of highlights supplied by various parts of the IDE.
If this is still a problem in recent 6.8dev builds (or 6.8beta) please reopen and use Profile Me! and attach the profiler snapshot here. Thanks http://wiki.netbeans.org/GenerateThreadDump#section-GenerateThreadDump-ProfileMeNowSinceNetBeans6.7
