Hi Brian,
Calling the XP interface a "rich" user interface is actually quite correct. It
costs a lot more and aside from making things pretty, adds nothing to the
functionality of the base item. Efficient and functional is beautiful too.
There are 2 good reasons for not even considering running any of the special
effects on terminal services. The first is an increased CPU overhead and the
second a significant bandwidth utilization increase. ANY animation, be it fades
or whatever has an overhead and across a WAN will produce a perceived reduction
in performance. Updating bitmaps takes cpu, bandwidth and time.
Log in via a WAN connection, use Excel, enable "feedback with animation" and
insert a column in a spreadsheet. Now do it with "feedback wih animation"
turned off. Which one's better?
Users will complain a lot less about a plain user interface than they will if
it's slow.
The latest client, with MPS 3.0 does support other skins for seamless apps, but
that overhead is largely borne at the client end so doesn't have a significant
effect on performance.
regards,

Subject: [THIN] windows 2003 seamless apps running on XP desktops...
hi list,
I understand that the XP theme is not available by default on windows 2003
servers. I assume this is because you don't need a rich user interface on a
server. Ok, well if that server is a terminal server then you do potentially
want that rich interface (for well connected ICA/RDP clients).
So, my question is this, does anyone know the level of overhead required for
the XP look and feel relative to the classic stylie? I guess the overhead
here is two fold, firstly, one CPU overhead to render rounded corners and
other XP 'stuff'... and the other overhead is in transmitting this down an ICA
channel, i.e. does it actually require additional bandwidth.
Also, what would happen with transparent windowy bits I understand the win32
client released with FR3 for xp included support for LUNA (.net) seamless
apps, although ... I've never tried it...
any thoughts on the subject appreciated...
Brianos :o)
