If I'm reading correctly, you're saying the X server is not multi-threated?
Yes. But that isn't really what matters here.
So if you're using sunray in a VDI project, the sunray server only forwards
RDP connections to the sunray thin clients.
Yes. Thus you essentially have two *processes* *per connection* that do
real work: the X server and uttsc.
In this case a dual-core should
be sufficient: one core for all solaris stuff and the other core for the X
server. Adding more cores will not make a big difference.
It will enable you to serve more connections at the same time.
A x86 would be the
best choice as it offers the highest speed per core.
Am I correct or do I see it too simple?
You missed that there is one X server per session.
So more cores will help with scaling to more sessions. But to get good
responsiveness in each session you need some level of per-thread speed
as well.
If a single screen update (switch a workspace, open a window, scroll one
page, ..) takes too long, users will complain. But, unless you play
video in all sessions, these will come in bursts so you can handle
several sessions on a single fast core. You still need more cores,
processors or hosts to handle more users. But you can't trade
single-thread speed for core count beyond a certain limit.

I'm saying both. To say that, "Well, it's not a good Sun Ray server
because the X server (and most applications!) aren't multi-threaded" is
putting it backwards.
