hello ono1 i do not expect significant differences in speed on file based access between cifs and nfs. you could eventually try block-based access via comstar-iscsi (client included in vista).
more important is enough ram to serve streams from ram or to use a streaming optimized (web-)server. zfs needs cpu-power and a lot of ram to become speedy! gea napp-it.org // free zfs server with web-gui -- This message posted from opensolaris.org
