I am trying to setup Wyse VDA and see how it works.
– installed the software on server and client
– With VDA, I see the CPU is very slow on the server and the video is coming up slowly as compared with NO VDA
– Any clue on what is happening here will help.
– How can I verify VDA accelerates RDP ?What client? You do not have to install it on a WTOS client. It is inbuild.

Hi ,
Thanks for the reply. I am running a Windows XPE on a Wyse V90L hardware. I see slow performance in
– PPT
– MS Word
– IE scroll
– VideoAlso when I capture the packet using a network monitoring tool, I do not see the default UDP port 3471, it is 3998 instead.
Do a PING from the client to the server and check the time it needs. There is a value in the registry for VDA which tells it when to jump in and when to ignore.
I guess your latency is just not big enough and it is just a bandwidth issue.CG
Hi,
Thanks for the reply. Yes, the RTT seems just 1ms in my network, so I changed the VDA registry on the server to have Latency Threshold as 0 and VDA began working, however it was still slow.
The max session bandwidth, I increased and saw 15% improvement in the VDA performance.
Does VDA need a huge bandwidth to work ? Mine is 100 Mbps LAN link and with session bandwidth as 29Mbps, still the performance is not 100% good.
Please let me know if I need to change any other parameters.
Ok, finally on debugging, see the Server is sending very slow packets, because of which the Wyse Thin client shows up slow video.
Any reason for why Wyse VDA Server will be slow ?
Please enlighten.I was on holiday for a week so couldn’t answer.
VDA is designed to work in FLP (Fat Long Pipe) networks. This means it needs at least 768 KB of bandwidth and can only play its acceleration card when the latency is bigger then 250-300 ms. VDA is not designed to overcome network issues with small bandwidth. It only works well in networks with latency or packet los issues.
