In a freshly installed RTP 6.1 machine, fs-cifs only writes at about 10KB/s
to my Win2K server, but it reads at “normal” speeds. I can FTP in the same
direction at about 2,000KB/s, so I don’t think it has anything to do with
the network configuration.
Other machines can write to the same share at normal speeds, including a
QNX4.25 box running SMBfsys.

Has anyone else run into this? Any fixes?
Are you using the devn-speedo network driver, for Intel chipset network
cards? I’ve had major intermittent performance problems with that.
Apparently there’s a new version on developers.qnx.com somewhere.
We’ve seen issues with MS stacks being too agressive with delayed
acks that lead to issues like this. fs-cifs has been patched
internally to set TCP_NODELAY to work around this. Will appear
in 6.1.1.

Nope, not using it. Like I said, my FTP performance is OK, so I’m
suspecting fs-cifs, not the network drivers.
