Hi, was anybody able to tune the Samba service (2.2.12 or 3.0.23b) so that it would perform out as well as unter linux where it maxes out at about 11 Mb/s using some Intel/3com card? So far, the most I got out of it was ~6 Mb/s while txing one file to a win2k station, curiously I get ~8.5 Mb/s when txing multiple files in parallel. So far i messed with: - ifconfig mtu - net.inet.tcp settings - smb's socket options Tuning SO_SNDBUF gave only very little gain, adapting the mtu to match the win2k box was useless. W/a net.inet.tcp.inflight.enable enabled the txrate is 2 Mb/s lower, however 6 Mb/s is still SLOW. I cant find the bottleneck, as the system is quite idle. Any Suggestions?
