Both directions.
I've made another little tests. I've again copied the same test-file to 
the samba-server (still 7MB/s) and my MacBook (which runs the 
Apple-provided version of Samba) (still over 20MB/s with 40MB/s peak) 
and vice versa.
Then I copied the same file to and from the samba-server, but with ftp 
(proftpd running on the fileserver) and guess what: 45MB/s!

Does Vista maybe under some circumtances use some kind of screwed up 
fallback protocol, which is so much slower than it should be? Even over 
100Mbit fast ethernet I should get more than 7MB/s!
I'm beginning to believe, that M$ wan't to tell me, to use their 
overpriced so-called "server software". :-/
