Neal Xiong and I worked on some testing code using Matlab using VCL
2.1 (and 2.2.1). A simple script loop was run with intermediate
output being displayed to screen, or with intermediate output
suppressed (and just the final result being displayed).
A small iteration runtime might takes 30-40 seconds (e.g. when
"counting by 10" to 5,000) and having all intermediate results
displayed to screen.
When we suppressed that intermediate results display (and just the
final result was displayed), the runtime dropped to 1-2 seconds.
Did seem to bear out the fact that asking VCL implementation to
display interactive type results (at least in our testing of images of
Matlab on Windows XP or 7) using RDP, would need to consider user
display output as a factor to be considered.

We've just started testing a third party RDP accelerator called

Ericom has been around for a while, and I've talked with others who
are using it successfully.
Personally, I've not had a chance to test it with GIS, but have tested
it with Solidworks CAD renderings and we've seen a much better
performance over RDP.

Just curious, has anyone tried using VNC to see if it helps. If I
remember correctly, VNC has the capability to refresh a subset of the
screen and hence may perform better.

We have the same issue here with the GIS software. It's due to RDP
has to
refresh the whole screen shot. The GIS software works much better

a Cirtix or VMware VDI that doesVmware PCoip that only needs to

parts thats being used.
RDP does has it's down faults.

Hi Amit,
There will definitely be delays in screen refresh rates as a
result of the
RDP connection, so if, for example, you're dragging a map or
other objects
you may notice some lag. You might try adjusting Windows visual
settings
for "best performance" from the System control panel.
There are also "performance" settings on the RDP client itself.
Try
opening Remote Desktop Connection and manually entering the
connection
information -- depending upon your platform, the RDP client
settings for
performance will be in a different tab.
GIS software can also be doing a lot of number crunching.
(Confirm the
specs in Windows System control panel on the client VM if you
haven't
already to make sure the proper resources are assigned by VCL.)
Have you
run any other applications in the VM/VCL environment that
experience
similar issues?
Regards,
Mike

Dear All,
I have run into issues of software(GIS) being slower on VCL as
opposed to
Laptop. Although I have 8GB RAM and 2 vCPU assigned for this VM,
comparison
of few tests resulted in poor performance on VCL. It could be
the nature
of
GIS and RDP or something else.
I have tried to isolate GIS vm's onto one blade and no other
vm's end up
on this blade.
Any ideas or options on how could I track this down to identify
what
could
cause this.
Thank you,
Amit
