Re: transfer between win2k and debian
I talked to a network admin who told me never to expect to get
anything like the nominal throughput from ethernet. I think 100Mbps
can make the disk the limiting factor. Of course, you shouldn't
expect to get the nominal disk performance (which is a peak, burst
value) either. :)
I would expect ftp would be much stronger than samba for doing the
file transfer. You can monitor the throughput using things like
statnet on Linux and 2K's performance monitoring tools. Or use a
stopwatch!
Still, you would think you could do a little better, at least if you
are transferring large files. If it's lots of small ones, you lose a
lot of time in set up. You might also check the fragmentation (W2K
has a built in tool for it).
I also have encountered some weirdnesses with SAMBA running atop NTFS
(I have a dual boot machine). Certain directories (no obvious
pattern) just aren't visible to the SAMBA client. Also, it's slow,
and I wonder if the NTFS driver could be a bottle-neck.
Just to be clear: I have a machine running Linux, with some NTFS
partitions that I mount under Linux. Then I serve those mounted
partitions out using SAMBA, and I look in at it from another machine
running NT.
It hasn't been worth it for me to trouble-shoot the problem, but if
anyone has any ideas ....
