Recently we ran a test with thirty employees simultaneously using
their Sun Rays (DTU ) from home and the performance varied per user but
in general the performance was poor. The DTU connects to the VPN
gateway and then to the sunray servers. We have three sunray servers (
Two V240 on one T2000) all running Solaris 10 5/09 all have 1G network
connection. Most users then use uttsc (Sun's RDP software) to connect
to their desktops. I am trying to find out what is causing the
performance issue. The issue did not seem to be the sunray servers so I
thought it might be a network issue, like packet fragmentation or VPN
gateway bandwidth. Our VPN gateway is a CISCO box with a 115Mmps
internet connection. What would be a normal VPN gateway bandwidth
allotment for DTU ( 400K) ? How would you know if it is a
fragmentation issue ? Any suggestion to improve performance would be
appreciated. I wrote a simple script to gather DTU info (it still
needs a little work) but let me know if you want it. The script uses a
combination of mconnect, utquery, utcapture and utdesktop.
