1MB/s is an optimistic average, and not realistic when you’re moving a model.
A quick and very unscientific test provides the following:
In Horizon VIEW, using a fullscreen CAD application on a 1920x1200 display rotating a model to locate a specific part or point on the model, the network spikes to 15 - 18Mb/s.
I tried with 3 different applications and 3 different models and as you’d expect the results are the same for all.
Also, same results when running wireframe or shaded.
The thing to bear in mind though, is that these are burst values, and that when you have multiple users on the wire, it’s unlikely they’ll all be doing the same activity at the same time. When the model’s not moving, it’s using 0Mb/s so it you’re taking a measurement, or checking materials, or some other motionless activity, then your usage drops.
So, if you can give each user the chance to burst to 15-18Mb/s and measure utilisation across a link with multiple users working normally that would give you a better value.
I’d suggest that realistically, for multiple users you could run closer to 5-8Mb/s as long as the capability to burts to 20Mb/s is present.
Citrix HDX is more efficient across the wire, for the same test as above it was using under 3Mb/s, so if bandwidth is a limiting factor it may be worth taking a look at that, and as you can see from Tobias’ results it could require even less.
