We have a set of Swingmark benchmarks to track the GUI performance, for the
latest Merlin build (jdk1.4 b46), we see more than 40% slowdown for only one
of the sub-benchmarks (TextArea Test), while other sub-benchmrks are steady
or speed up over 1.3.

The benchmarks are located in:
  /java/jdk/ws/performance/MASTER/perfteam/swingmark/

It would be best copy the benchmark code to a local disk to repeat tests.

each row in above tables represents the scores (spent time) for each sub-benchmark(over 5 runs). Look for "TextAreaTest" row, average the times for
both jdk1.3 and jdk1.4 runs respectively, you would get the slowdown number.
