Benchmarking Software's on VCL
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
Re: Benchmarking Software's on VCL
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?

Re: Benchmarking Software's on VCL
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 with like a Cirtix or VMware VDI that doesVmware PCoip that only needs to fresh the parts thats being used. RDP does has it's down faults. -Alex On Mon, Apr 16, 2012 at 6:56 AM, Mike Haudenschild m...@longsight.comwrote: 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.

Re: Benchmarking Software's on VCL
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.

Re: Benchmarking Software's on VCL
We've just started testing a third party RDP accelerator called Ericom Blaze. http://www.ericom.com/ericom_blaze.asp 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.
