Sluggish Performance When Form Contains Many Components

[reconway]

I'm getting VERY sluggish performance from the IDE when I have large numbers of components on the form (ie, 50-100 labels & fields). Every change to a component's location or property results in a pause of 3-5 seconds before it takes effect and the editor is ready for another operation.

I'm using eclipse 3.1M7 with Swing Designer build from 25 May 2005.

It looks like the CPU goes crazy after every action - causing the slow response. I have plenty of RAM and the eclipse is started with -vmargs -Xmn250M -Xms500M -Xmx500M. I'm going to roll back to the previous snapshot of Designer and see if I still have this problem.

Any exceptions in your Eclipse .log file?

What layout manager are you using?

Can you send us a test case so that we can reproduce the behavior on our end?

I'm using JGoodies FormLayout - but I have the same performance problems with other forms using <null> layout. I will forward an example form with required libraries for your review.

Thanks!

No exceptions in the log file. I've also noticed that search & replace is sluggish as well. If I switch to the standard eclipse Java editor it is very fast, so I'm guessing that the slowdown has something to do with the round-tripping between the code and the gui.

This problem has been confirmed and fixed in the latest v4.0.1 build.

That fixed it. Thanks again for the excellent/fast support!
