I've created a test-volume on this fileserver (c-hoernchen). It is
currently mounted on /afs/wu-wien.ac.at/tmp/afsdelays. It's subdirectory
"t" should be writable for system:anyuser.
Maybe this volume could be useful for testing...

I am able to reproduce the delays with the following command:
cd /afs/wu-wien.ac.at/tmp/afsdelays
./delaytest.pl

Btw. I've found out that clients on AIX (5.2., oslevel 07) also show the
same problem.
However Windows Clients (Version 1.4.0008) don't suffer from the delays.

Cheers,
