#2383 — bad JRE performance

  To: comp.lang.java.gui
*every* java program (not only mine) with swing gui has *very* slow 
update process (about 3 frames per sec) when I change the window 
(resize, scroll the scrollbars etc).
I see when a window draw itself from up to down slowly.

I haven't this problem in my older PCs so I believe it's some kind of 
hardware problem? Maybe graphics card?


JRE 1.6.0
Intel Core2Duo 2.14GHz
ATI Radeon X1950 Pro
2 GB RAM

  I have a similar hardware configuration and saw similar behavior when 
I has Google Desktop running on the desktop.  I suggest you compare 
performance with an empty desktop and your normal setup.  I was able to 
solve my problem by simply iconizing google Desktop.

I have WinXP with old theme, no background, best performance choices.

Strange.
The problem doesn't appear always.
But when appears, the scrolling of window takes 50% of my dual-CPU (one 
of two processors 100%)
Normally takes about 1-3% of one processor

The problem fixed temporary when I maximize-restore, but not always.

Silly.
I have a Core2Duo 2.14GHz and java programs run faster on my Athlon XP 1600.

Check your video driver config.  Look for turning off acceleration,
turning on/off DirectX.

Check for driver software update.

Try a different driver card.

It seems, than only when I have a non-default L&F the problem occurs.
I have Windows Classic and most of times, performance sucks.
When I switch to metal, performance doesn't suck.
The same with other programs.

Wrong. I have it again.

Perhaps some other program is interfering. Try booting with anything
non-essential suppressed.
