Now the heap usage after the forced garbage collection

is at 138 MB.

BTW, I increased the xslt transformer pool size to 64 which
makes the test run a
lot faster, but will certainly influence the memory usage.
I'll keep this
setting for further test.

Now the largest object is the ContinuationsManagerImpl with
a retained size of
34 MB, followed by the DefaultTransientStore with 17 MB.

There are still more than 800 SessionImpl objects, connected

DocumentIdentifier shouldn't keep a reference to the

After another half hour, a GC pushes the heap usage down to
184 MB. I guess some
of the continuations have been removed.

But why did 444 sessions create 82.456 DocumentImpl objects?
I can't imagine
that all of them have been requested by the Create usecase.
Does the sitetree
acquire DocumentImpl objects unnecessarily?

It looks like the remaining objects are hold by
continuations. That's a
different issue.

I just ran the test with 20 threads, each creating 50
documents. It finished
without an OOME.
