I am not saying that this architecture is the only viable one, but it does work for TCP for sure (and performs reasonably well too)

Another Quote:

The whole task of optimizing performance beyond, say, 20-50K packets/second per box tends to be Quite Elaborated, and involves quite a few things which are platform- and hardware-dependent.

Making 3D work is not easy to start with, but making it look good is a major challenge.

Another Quote:

In such cases of dual visual interfaces, it is paramount to have Logic-to-Graphics layer as described above

Abstract:

2D scaling is a headache.

Quote:

For us (as developers) it is important to know that the difference does exist, and that we should be ready to store graphics with larger sizes even when we personally don't see the need to do it.
