A school laboratory or large enterprise may use VMware on workstations; students may engage your Adobe Connect Virtual Classroom from VMware-based clients. Clients will perform as follows based on our testing.
Adobe Connect has settings for quality that affect both the video (webcam) being shared as well as screen sharing. I have indicated the quality in the Settings column in the table below. The VDI client tested was the participant (not the host) in these tests.
Test Type | VDI CPU | VDI RAM | Settings |
Idle Room | 30% | 58% | There was no activity in the room of any kind. |
Webcam no content | 55% | 56% | Adobe Connect video quality set to standard (see layout screenshot labelled “Webcam only”) |
Webcam no content | 70% | 56% | Adobe Connect video quality set to high no change in pod size |
Screen Share no webcam | 60%-80% | 56% | Adobe Connect screen share quality set to high with the monitor that was shared resolution set to 1400×1050 (see layout screenshot labelled “Screen share only”) |
Screen Share no webcam | 40%-60% | 56% | Adobe Connect screen share quality set to high with the monitor that was shared resolution set to 1024 x 768 |
We can draw a few conclusions from these tests.
- Firstly, the quality setting for the video had an effect on the CPU utilization.
- Secondly, even though the quality of the screen share was set to high the resolution of the monitor that was shared also had an effect on CPU utilization. In other words the higher the resolution the higher the CPU utilization.
- Thirdly, we can infer that it is prudent to make sure that all students on VMware-based clients shutdown all other client-side applications while engaging with an Adobe Connect Virtual classroom to avoid resource contention.
