-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 As I keep telling our Sun reps and support this is a big issue for us and a large complaint from students. And if students are not happy, then the Sunray looses. And as I have seen, once a student has had a bad experience with a Sunray they do not go back to them.

We use Citrix for connecting to our Windows session (so using the ICA protocal I think) and see about the same transfer rate as doing straight from the Solaris desktop. But in Windows if the file is too large it will fail. I forget now the sizes where it failed. One thing is if the file is < 5MB you get fairly good transfer rate. But once it's over 5MB the rates drops down significantly. You'll get > roughly the same performance as Sun Ray. These were meant to save a > small file or two, not really large files.

If they have large files to get off of thumb drives they need to go to one of our PC labs to save on their network drive space. > > Michael Jinks wrote: >> On Fri, Jan 09, 2009 at 02:25:29PM -0700, CJ Keist wrote: >>> We have seen the same poor performance in transfer speeds with USB >>> thumb drives.
