J2SE Version (please include all output from java -version flag):
 java version "1.4.0-beta3"
 Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-beta3-b84)
 Java HotSpot(TM) Client VM (build 1.4.0-beta3-b84, mixed mode)

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

Operating System Configuration Information (be specific):
 Sun Ultra Enterprise running Solaris 8.0

Hardware Configuration Information (be specific):
 4 CPU's @ 400MHz each and 3072MB of RAM

Bug Description:
 Attached simple Java application(PerfTest.zip) shows a significant
 degradation of performance from JDK 1.3 to JDK 1.4. Under 1.4, on big
 system(4-way machine), it takes 2-4 milliseconds to create; under 1.3,
 the times are 0-1 ms. On a small system(1-way machine), the difference
 is even more obvious. Under 1.4, it takes 6-8 milliseconds to create;
 Under 1.3, the times are 1-3 milliseconds.

 Here are the test results:

Steps to Reproduce (be specific):

The attached zip(PerfTest.zip) file includes sources, jar,
build.xml (for ant build) and a 'testTime' script. This test simply loops x
times (100 is default), creating AMOL1Code objects and printing out how long
it takes to create them.
