Hi Volker, I am using the following socket options:
socket options = TCP_NODELAY IPTOS_LOWDELAY SO_RCVBUF=65536 SO_SNDBUF=65536 I've been testing with lower rcvbuf and sndbuf values but this seems to be the best. Any advice on how to calculate this value besides trial and error? Following is my smb.conf: [global] workgroup = Workgrouplasp encrypt passwords = yes security = user smb passwd file = /etc/samba/smbpasswd netbios name = LASPFS server string = LASP Linux File Server dns proxy = no log level = 1 oplocks = yes level2 oplocks = yes socket options = TCP_NODELAY IPTOS_LOWDELAY SO_RCVBUF=65536 SO_SNDBUF=65536 guest account = samba map to guest = Bad User map to guest = Bad Password read raw = yes write raw = yes max xmit = 65535 dead time = 15 getwd cache = yes interfaces = 192.168.1.5/255.255.255.0 bind interfaces only = yes socket address = 192.168.1.5 max protocol = SMB2 [laspfiles] comment = Public File Storage browseable = yes force user = samba force group = samba path = /srv/samba/filestore/laspfiles read only = no guest ok = yes My focus was to tune the fileserver for several 8MB file transfer. Any idea on how to improve this? Thanks for your help!

Do you have "socket options" set in your smb.conf?
