Start up and repaint delay

Postby detorres » Wed Aug 18, 2004 4:37 pm

There's a very significant delay at start up and any time the frame is completely covered and uncovered during which the contents of the frame are completely gray. I am using JDK 1.4.2_04 on Windows XP (with less than a screaming machine). Have you seen this problem? Are you using the system look and feel? I don't know if it has anything to do with XP, but I discovered that creating LARGE buttons is very slow with the XP look and feel. Maybe there are other problems with it that are slowing down YJP.

Are you experienced with such delays only when stopwatch is displayed on the backgroud (or even if snapshot file is opened)?

It looks like it's only when the stopwatch is displayed. CPU load goes to 100% (on Windows XP) for as long as about 10 seconds sometimes.

Thank you for pointing direction to dig. BTW, couldn't you please do the following:

- launch profiler with yjpagent with CPU profiling enabled
- 3-4 time repeate the delay
- capture CPU snapshot
- send us this zipped snapshot.

this CPU snapshot would be very useful for us, because in our environment everything is fast enought, so I suppose that Java2D works a bit different in our case (perhaps hardware acceleration in a problem)
