That's exactly why I did not use the "default" columns of the Task
Manager, but "virtual memory size". I now compared the numbers to the
"private memory" column of Process Explorer, and Process Explorer shows
about 800k even more usage the the Task Manager.
It is still about 5 MB of private memory per "idle" backend process. Is
there anything I can do to optimize?
Thanks again,
