I think there are a lot of production / media companies that require 1Gig / 1Gig - With online production all over the world, in-flight material processing, contact with multiple media at once, such requirements are welcomed.
This speed allows us to work freely. And so the GX20 is not a device designed for this. 500 MB / s would take care of most of the needs, even the most demanding ones. Where efficiency matters, we use other Cisco products :). I just have the GX-20 at home, where I have my workplace . However, in other locations we have much more efficient equipment.
I wanted to improve my working conditions 🙂 and the GX-20 is a nice and simple device that I did not have to waste time on 🙂 Unfortunately, I was lost by my ignorance and I did not check its performance 🙂
