However, 9MB/s on your > link is not bad at all, one has to consider the protocol overhead. I get 25 to 30MB/sec between FreeBSD 6.0 and Windows XP clients with tcp.inflight disabled and interrupt polling enabled on a 1gb link without jumbo frames. The various Linux distributions do about the same on this hardware - 3ware striped raid arrays, dual xeon, and 2Gb ram. in smb.conf I'm using: socket options = TCP_NODELAY strict locking = no use sendfile = yes 6.1 should be easier to tune in that tcp.inflight is selectively disabled by default for low latency (LAN) connections.
