Hi Brian,
Sorry, came on a bit heavy.
There's nothing intrinsically wrong with the XP interface, except for the huge
waste involved in supporting visual effects. Get a really old machine and run
XP on it with My Computer > properties > advanced > performance set to either
best appearance or best performance. Where CPU is limited, it makes a huge
difference to the perception of speed.
However there's nothing wrong with the XP user interface once animations are
disabled.
Just include the following unmanaged policy snippet in your TS policy
templates, disable visual effects and you can have the best of both worlds.
--------------------------
CLASS USER
CATEGORY "Visual Effects"
KEYNAME "Software\Microsoft\Windows\CurrentVersion\Explorer\VisualEffects"
POLICY "Visual Effects"
PART "Disable Visual Effects" CHECKBOX
VALUENAME "VisualFXSetting"
VALUEOFF NUMERIC 0
VALUEON NUMERIC 2
END PART
END POLICY
END CATEGORY ; visual effects
-----------------------
regards,
Rick

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.
[Lilley, Brian] very true indeed.
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.
[Lilley, Brian] I totally agree, that a TS design should cut out
unnecessary flashy gizmos, but, at the same time we can't remain with legacy
look and feel. Is the XP look and feel really going to cost that much?
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?
[Lilley, Brian] I totally agree.
Users will complain a lot less about a plain user interface than they
will if it's slow.
[Lilley, Brian] Absolutely, however will the XP look and feel cost that
much?
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.
[Lilley, Brian] ah, ok... so does that mean we can have XP look and
feel at little cost.

Rick

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)
