Even though the line is 100Mbps, the firmware only does USB 1.1 which is 11Mbps. However, in my experience, I don't get near 11Mbps either.
On a home LAN, two laptops running Windows XP with one on wired 100 Mbps and the other on 54 Mbps full speed 802.11g wifi, a data transfer from the wireless to the wired laptop of 15.5 MB through RDP storage redirection took about 15 seconds. That comes out to 8 Mbps, which is still better than what I have seen with a Sun Ray. The ~1.5 Mbps rate for Sun Ray USB earlier seems to match up with what I remember, unfortunately I don't seem to have written down my results from when I tested before.... As it were though, I think it's related to the fact that the server is talking to a block device over the network using a protocol that isn't really optimized for the network. Perhaps it's possible to implement something iSCSI-esque in the firmware instead of what's in use now? I suspect that there are inefficiencies that can be worked out. But just to echo what's been said, we feel awkward every time we have to tell our users "use a Windows computer to copy your files, they are too large for the Sun stations."
