Hi,
The small program I wrote continusly requests a URL from a web
server. I let it run until it has made about 1000 requests (so
that the server will get loaded) and then I try to load a not-too
small page (while the program continues to run).

The reason I used the management screens with all the folders expanded
was so that it will be bigger in size and would be easy to be reproduced
by anyone in this list.

Have you tested it on heavy load?
If it's not a big problem, maybe you can run my program and tell me if
you experience similar performance issues.
