I am experiencing a "one-way delay" in file transfers from Microsoft Clients
(Windows 95 and Windows NT) to Samba.
FreeBSD 3.3-Stable as of Oct 8 1999
samba 2.0.5 installed from the ports collection
smb.conf includes this line:
socket options = TCP_NODELAY IPTOS_LOWDELAY SO_SENDBUF=16384 SO_RCVBUF=16384
(originally it had just 'TCP_NODELAY'
but I added the others per suggestions found in on-line resources)
Network is a 10/100 Mbps Bay Switch with all below running 100 Mbps
-------------------------------------------------------------------------
Client Send 1MB to SAMBA Receive 1MB from SAMBA
copy e:\test\file u:\ copy u:\file e:\test
------------------------ ---------------------- ----------------------
Microsoft Windows 95 15 seconds Instantaneous
Microsoft Windows NT4 15 seconds Instantaneous
IBM OS/2 + TCP/IP 4.1 Instantaneous Instantaneous
-------------------------------------------------------------------------
(IBM OS/2 TCP/IP 4.1 is an optional IBM TCP/IP stack for OS/2
which IBM describes as a "BSD 4.3 stack")
I had mentioned this at FreeBSDCon, and several people had suggestions,
most mentioned the "TCP_NODELAY" option.
I still see this delay.
Do others run 3.3-Stable and Samba also see this type of delay?
Are there other suggestions for solving this trouble?
