We have motion capture machines trying to pull files from a server. The current system uses Irix running 2.x and I am trying with my Linux box and 3.0.2a. The loading of the files is quite slow, much slower then when loading the same scenes being shared from a Windows machine. When I use ethereal to watch the traffic, there's a lot of 512 byte packets, and that stuck out as odd. I turned some debug on the logging, and see: [2004/05/20 16:00:59, 3] smbd/process.c:process_smb(890) Transaction 1965 of length 63 [2004/05/20 16:00:59, 3] smbd/process.c:switch_message(685) switch message SMBreadX (pid 12400) [2004/05/20 16:00:59, 4] smbd/uid.c:change_to_user(122) change_to_user: Skipping user change - already user [2004/05/20 16:00:59, 3] smbd/reply.c:send_file_readX(1949) send_file_readX fnum=5936 max=512 nread=512 I am wondering if there's anything that stands out here as wrong, or at least somewhere to start digging for a solution? The SMB shares are all mounted via NFS, from a NAS device. We are not using AD on our w2k servers. my smb.conf: # Global parameters [global] workgroup = MAINFRAME netbios name = MANDARIN security = DOMAIN encrypt passwords = Yes password server = neptune, pluto passwd program = /usr/bin/passwd %u passwd chat = *ew*password:* %n\n *e-enter*new*password:* %n\n max log size = 5000 socket options = TCP_NODELAY IPTOS_LOWDELAY SO_SNDBUF=32768 SO_RCVBUF=32768 load printers = No log level = 2 os level = 0 local master = No comment = Samba %v print command = /usr/samba/bin/sambalp %p %s %U %m lppause command lpresume command [MOCAP] path = /mocap writeable = Yes create mask = 0775 force create mode = 0775 directory mask = 0775 force directory mode = 0775 inherit permissions = Yes
