Hi,
I suspect some of this has to do with the
changes to the embedded Tomcat, and some
upcoming deployer changes.
Probably calls are becoming non-optimized
due to some classloader issue that is to
be fixed in new deployer.
But I don't use Tomcat, so I am not sure.
For the JTA changes, these seem to me to
have the same performance as before.
These changes do touch the invocation
layer, but not in any way that should
result in optimized calls becoming non-
optimized, or result in performance
degradation.
But the performance degradation you show
below for after my changes is heavy, and
I cannot say for sure that it has nothing
to do with my changes.
Depending on how much you checked out
from CVS, it could also be due to
dewayne's commit to module tomcat a few
hours later.
Unless someone knows something about
what is happening here, I guess I have
to learn to set up an embedded Tomcat so
I can see for myself.
Best Regards,
Ole Husgaard.
