Hi Steve,
Your comparison has one hop for the PC/Mac and two for thin clients.
Have you tried running the CAD tools directly on the Sun Ray server?

We are using Sunray3’s to access and run Cadence IC-CAD tools on Linux
servers.
that is: login in to Sunray, ssh to a Linux server, run Cadence on
the Linux server.
What I see is: opening a cell layout, or panning around the cell layout
using the Sunray3,
takes ~8x longer than the same task on my 2011 i7 MacbookPro: =ssh to
same Linux server,
and run Cadence on the same cell data, on the same network.
Also, the Sunray3 takes about 2x longer on the same task as from my Win7
PC with
Xmanager/Xshell(xterminal) to the same Linux server.
Now in both the Macbook case and the Win7PC case, there is local graphic
processing,
where the Sunray does not have much(any?) graphic processing. The
Sunray3 just takes
the pixel-data, that it receives( packed in UDP, I think ) and sends
that to the monitor.
So my question is, does this sound reasonable ? for CAD data to take
that much longer
to draw and pan, compared to a MacbookPro or a Win7 PC ?
Note1, our SRSS was updated last fall, so I think we are up-to-date on
the server software.
Note2: I have tried this same experiment with two 10ZiG(PC-over-IP)
thin clients(Tera1 and Tera2 chipsets),
and I get the same results I get with the Sunray3.
--> this leads me to believe the Sunray approach and the PC-over-IP
approach(both sending pixel data
over Ethernet) are not going to work with CAD data.
Could it be the case that Sunrays were never intended to be used for CAD
tools ?
Or, is it possible we are missing some switch on the Sunray server that
would improve the video performance ?
thanks,
