The performance data running a benchmark with iAS7 on jdk1.4.0 show that
server jvm is a lot slower than client jvm:
    7.167 pages/sec client jvm
    2.38 pages/sec server jvm

-Xprof data then indicate that it could be optimize/deoptimize loop problem
with server jvm. GC doesn't seem to be the problem as shown in the GC logs.
-XX:+TraceClassLoading also confirms that no class is loaded whence
the iAS7 server gets started.

All log data (-Xprof, -XX:+PrintCompilation, -XX:+TraceClassLoading) can be
found in:

We ran the test with JDK1.4.1 build09, the performance results are similair to
those of JDk1.4.0 (slighly improvement for both client jvm and server jvm):
    7.55 pages/sec client jvm
    3.29 pages/sec server jvm

And -Xprof data with JDK1.4.1 build09 shows that still thousands of
"UncommonTrapBlob" are in the server jvm log file. The log files are
