J2SE Version (please include all output from java -version flag):
java version "1.4.0-beta_refresh"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-beta_refresh-b72)
Java HotSpot(TM) Client VM (build 1.4.0-beta_refresh-b72, mixed mode)


Does this problem occur on J2SE 1.3? Yes / No (pick one)
No.


Operating System Configuration Information (be specific):
RedHat 7.1, Kernel 2.4.3, glibc 2.2.2, XFree 4.0.3


Hardware Configuration Information (be specific):
Athlon 1GHz, 256 MB RAM, Ati Xpert 98 graphics adapter


Bug Description:

The performace of drawImage on Image and VolatileImage objects in JDK 1.4 is
worse than the performance of drawImage on Image objects in JDK 1.3.1 (on
Linux using a local X server).


Steps to Reproduce (be specific):

Run the attached Java program(VolatileImageTest.java &
ImageTest.java) on JDK 1.3.1 and on JDK 1.4 and look at
the output.

Average times for blitting a 600x600 image in milliseconds on Linux (local X
server):

Image JDK 1.3.1: 6-7 ms
Image JDK 1.4cap: 17-19 ms
VolatileImage JDK 1.4cap: 17-19 ms

Not be able to measure the performance on a comparable Win2K machine using
this test (too fast).
