Netbeans 6.1 going slow on recent Open Solaris builds

Wednesday Sep 10, 2008

The Computer Science Department at Aberystwyth University are running OpenSolaris on their 50 or so Sun Ray lab backed by a T5140 and some V240's for their Open Source Computing Degree Scheme. In some pre-term testing, Dave Price from the Department found that Netbeans 6.1 was worse than glacial in performance terms, for example when you select a menu, it can take 30 seconds to get focus back. Few programmers have that level of reserve, even fewer students.

The cause is 6716640 and the workaround of unchecking the 'Do not show this page on startup' checkbox works a treat. I have yet to get feedback from Dave as to how effective the patching is.

Sure you got the bug ID right, Clive? That one doesn't seem to exist... SunSolve says "The application resource you requested could not be found".

I think we've seen a similar problem with Netbeans 6.0 on Solaris 10, although this is a startup-only issue - after a while it settles down and performs OK.

Check couple of things
1> Use jdk1.6 or higher ... it increases the graphics performance of Java Swing.
2> Check whether the amount of RAM is sufficient.
3> Install only those packs of Netbeans which you require, ie install web & java ee pack for web dev etc. Installing a full netbeans pack would require more memory and will be slow and unresponsive.

Phil, regarding the bugid, I think you need to be logged into SunSolve for it to work.
