Sorry, but I think this won't help Olaf much.

I've played a little bit with samba.1.9.18p10 (=3Dlatest at the time of
writing) an NetBSD-current. I just can't get more than ~1/3 of the
transfer rates I get with ftp (~340kB/s vs 1.04MB/s) on a switched

source-tree (I didn't use the samba-package) - didn't changed much

Well, I suppose Samba & NetBSD are just no big friends (at the
