Troubleshooting and testing RDP/PCoIP Performance

[admin]

Hi All,
We have a powerful ESXi Cluster that is currently hosting a test VIew environment with 3 Vista Virtual Machines.

We setup View, and have tested both PCoIP and RDP connections from our lab in another room.  We have a slight delay with the mouse cursor.  We are working to performance tune Vista (Aero is disabled, Windows Search is disabled, etc.).

In theory, everything is LAN-connected.  The lowest speed link in the network is 100Mb, but there are questionable Cat5e cables and questionable router/swithch configs in between the servers and the lab where our clients are.  I have reason to believe something is hosed on the network side, because normal day-to-day lab network performance is also slow.

I need to verify that bandwidth and latency are not issues.  I can test latency with PING.

Does anyone have any suggestions for testing the LAN with respect to RDP and PCoIP performance?

I'd like to know if both protocols are able to get as much bandwidth as they would like.

Thanks!

Found this - I'll give it a try to test bandwidth.  I've read it has UDP capabilities.

All,

I figured out that the issue causing my performance issues was that my test workstation had 5Mbps throughput back to the VM.

This was due to a router issue.  That has been temporarily solved and now I have 94Mbps throughput back to the VM, and View is performing much better over PCoIP.

This is the tool I used for testing throughout: iPerf

Solid Gold!

There is a new capability that will be available in the future that will tell you what the session sees the through put as. This should be handy as it will jus  be there and you can quickly check it or even remotely poll it
