I posted a while back about getting very slow writes. People suggested modifying (increasing) SO_SNDBUF and SO_RCVBUF and this actually helps enormously. However, there is obviously something still not right. Writes are still about 1/2 the speed of reads. This only seems to affect Win95 clients (NT machines are fine). Doing a write of a 20mb file to the server generates the following message: chdir to /int-data/...

Hi all, I have a mixed environment of Windows 2000, XP, Linux, and MacOS X clients connecting to various Samba servers. Our network is 100Mbit switched ethernet. Originally, we were using samba 2.2.8a, with the socket options of TCP_NODELAY SO_SNDBUF=4096 SO_RCVBUF=4096. However, the MacOS X clients (which were added after the initial setup and testing), had horrible file xfer performance; somewhere around 100kbit/second, while the Windows clients were much faster. The first response was to upgrade to samba 3.0.0, which didn't affect the problem one way...

...transfers over a long haul connection. The current transfer rate is limited by the TCP window size and the RTT. I looked at HPN-SSH, but that won't work because we don't control what software the peer is using. I was thinking about coding a much more modest enhancement that just does SO_RCVBUF for specific subsystems. In the interest of adding something that the OpenSSH community would take back into the source base, what do people think is a better fit in the configuration file? A single keyword for specifying connection options: SubsystemOptions <subsystem-name> [command-line-...

Hello list, I have observed quite low bandwidth usage when copying files over SMB. This happens for at least three cases I have tested: * Windows 98 SE reading from a Samba 3.0.22 smbd * Windows XP reading from a Samba 3.0.23d * smbclient reading from 127.0.0.1 (3.0.23d) According to iptraf, the average transfer rate was oscillating between 8604.60 kbps and 8654.20 kbit/s, copying a

...ughoutput about 3-4 MBytes/s reading from Samba, 2-3 MB/s writing to Samba server. (IDE discs, but 256 MB memory, Athlon 900 MHz, one 500 MB file, 100 Mbit network). What are your results? Does anybody knows about some performance tunings? I have adjusted only this: socket options = TCP_NODELAY SO_RCVBUF=16384 SO_SNDBUF=16384 write cache size = 262144 Thanks, Libor
