During a performance optimizing session this week, with a customer, we found some interesting things to boost specific parts of the environment. While playing a high resolution video with clipping where the whole screen turns black and shows a new screen a split second later.
When we started, we saw the video bump and freeze from time to time. Also we experienced ghost lines on the middle of the screen, where the upper part of the screen moved first while the bottom part tried to keep up. We used the Fast & Furious 6 Official Trailer in an 1080p format for testing. The the business news running in an embedded Windows media player on Internet Explorer 9 didn’t perform well either.
The vDesktop is a Windows 7 Enterprise desktop with 2GB memory and 2 vCPU so it can play native 720p videos when necessary as Erik mentioned in his post. We are running the VMware View environment on an Imtech built Flexpod with NetApp storage, Cisco UCS computing power and Cisco Nexus switching for VMware vSphere and VMware View 5.
