Have you compared file transfer times of other storage protocols
encapsulated in remote device protocols such as ICA or RDP? You'll get
roughly the same performance as Sun Ray. These were meant to save a
small file or two, not really large files. The best architecture for
people that save many or large files to to create a media station that
users can use.

We have seen the same poor performance in transfer speeds with USB

minutes to copy off of or write on to the thumb drive.
That sounds roughly comparable to what we're seeing.
I have put in
support ticket to Sun on this issue. Bad news that came out of that is
that there is no fix for this nor any time frame given when there might
be one. We have had this issue since Sunray server 2.0.
Bummer...
One thing Sun Engineering told me is even though the DTU says USB 2.0
support (Sunray 2FS) you will not get the 2.0 speeds since the DTU only
has a 100Mb network card.
Our network is generally 100Mb at the edge, but we get far higher file
transfer rates when we aren't using Sun Rays. There has to be more to
the story than that.
But that still doesn't account for the slow
speeds we see as well.
Indeed.
Well, at least this suggests that it's not a problem with our setup, but
a problem with the apparatus as provided by Sun. My bosses, colleagues
and users aren't going to like that answer but so it goes.
