Profiling both without Burst (vanilla C# code) = 0.3ms for 1146 vertices:

Profiling with Burst = 0.062ms for 1146 vertices:

While not great data for drawing conclusions, it's still fascinating to observe the order of magnitude in difference! It halved the time my Update() loop is taking even at these tiny numbers! I suspect with greater numbers of vertices, this would grow even more impressive!
