Hi Volker,
thanks for the fast reply. So used the strace command. I am not so a strace
specialist but is it possible that the problem are the many polls?`
12513 15:33:24.593065 poll([{fd=9, events=POLLIN|POLLHUP}, {fd=7,
events=POLLIN|POLLHUP}, {fd=40, events=POLLIN|POLLHUP}, {fd=32,
events=POLLIN|POLLHUP}, {fd=34, events=POLLIN|POLLHUP}], 5, 4436) = 1 ([{fd=32,
revents=POLLIN}]) <0.002497>
12513 15:33:24.595615 read(32, "\0\0\0T", 4) = 4 <0.000017>
i added a link to the strace. I dont see which syscalls take long. There are
such many syscalls in any second so i dont know whats normal. :-|

Do a
strace -ttT -f -o /tmp/smbd.strace -p <smbd-pid>
and see in /tmp/smbd.strace which syscalls take long.
