indeed, a 32bit application works on 64bit windows, testing with the
netio tcp/ip
benchmark and SDP I have a remarkable performance gain.
Now it's time to find the appropriate Fileserver and Client Applications.
I have not found a NFS client/server suite so far that could make use of
SDP.
Any recommendations for alternative filerservers are welcome :)
Are there already ways to determine that an applications makes use of SDP?
thank you

The new version of SDP that should be available soon will allow 32 bit
applications to run on 64 bit systems as well.
Thanks

Hi Tzachi,
I was considering an FTP Server at first, but it is not the right tool
for the job.
The Situation is the following. It is a multimedia/video editing
company.
They need to access raw HDTV material from their windows workstations
for editing
and playback. So FTP is not an option in this case because FTP
requires
a full download to local memory.
SMB/CIFS, NFS and maybe similar protocols seem to be the only options
for real time playback and editing.
Today I have tried tweaking the Windows XP TCP/IP settings by setting
the Tcp1323Opts option
and raising the TcpWindowSize to 512k. There was a little bandwidth
increase but still not enough.
If I am not mistaken using IPoIB on windows will not bring me near my
performance expectations(300MB/s) at the moment.
I will start trying the NFS(nfsaxe) over the SDP provider from
Mellanox
today.
My biggest concern at the moment is that the Server is a 64bit Windows
XP and the nfsaxe server application
is a 32bit executable. If I read and understood the SDP Documentation
correctly you can not use a 32bit application
with SDP on a 64bit Windows?
thank you
sebastian
So they need to work on parts
