This is another truth. That machine has a Sis card with no flow control.
Windows does not say it, but another same machine with Solaris 10 says it
during boot.
The strange thing is that the Solaris 10 machine works great anyway, with no
change on fd.
Why?

[Bacula-users] Solved whyWindows FD 1.38 sometime is slow
I had headaches for a week, tryingto figure out why some windows FDs were VERY
slow compared
to all the rest of FDs. These slow clients were all rating at around 1Mb/s.
After playing a bit with many system and bacula parameters, I decided not
totrust what was stated in the manual: "the default Maximum Network BufferSize
= 32768".
Because I tried rising this parameter to double default, both on sd and allfds,
and noticed that I had
a slow down of all the FDs, I put back everything to default.
Then I decided to explicitly set the "Maximum Network Buffer Size =32768" to
the windows machine
that was still so slow....and it magically started to work as the rest offds!!!
Beacuse I have another windows FD on the same installation, with the
sameversion of bacula, and this one was going fine with the default (MNB
notspecified), what I believe is that the windows setup has been built with
adifferent default (maybe 65536), and this setting may be fine only in
specificsituations.
What I mean, is that probably 32768 is fine for almost any card, but 65536
maybe fine only for cards
that support this buffer size.
What I know now is that explicitly setting the buffer to 32768 on the bacula
fdwill work.
After finding this, I did the same on other 3 installations where I had
similarproblems, and it worked!
Thanx to everyone that tried to help me.
Gabriele.
