As stated in my initial mail, I already tried using `smbclient`, and it
basically hits the very same speed-limit that the kernel's CIFS-implementation
Is there any canonical or recommended way to debug/profile smbd's performance
characteristica at runtime?
I'm not sure how looking into the transferred packets themselves could help
me, since the reason for the bad performance is either on the server (I'm
quite adamantly sure by now that the server, and smbd specifically, is the
root of the problem at hand), or the clients - not the wire or networking
equipment in between. If you can elaborate on the subject though, I'd be
delighted to listen and learn :)
Thanks very much for contributing!
