This summarizes testing data for the two experimental builds. The numbers
reported here are with JDK 1.3.1 Hotspot Server. I have attached the raw
data log, which also includes the same tests using Hotspot Client.
Interestingly, the behavior is almost identical; except for a significant
initial hit when first starting to use the James classes.

Basically, we're losing roughly 8.5K - 9K per 2050 1K messages. The test
uses a single connection which never closes (I push 50,000 1K messages
through it, and it doesn't run to completion before I stop the test).
I want to stress that this behavior is common to both builds and both JITs.
Getting the same results for this test as compared with the previous test
would seem to indicate that it is not dependent upon the number of
connections. The next test will use smaller numbers of large messages to
see if it is message count or traffic that is impacting us.
