    As I go back the drawing board for my data synchronization, what sort of entity structure should I develop. Assuming that memory is infinite, should I have a shallow entity structure where each entity contains a single float component or a deeper structure with an entity representing a float in multiple buffer elements?

    Obsessively buffer element has overhead. It depends on if you need to do stuff like sorting.

    Apologies, as mentioned in the other post, it's unfortunately not something we can easily answer. To even begin to, we'd need significantly more context about your data, requirements, limits, and project, and even then, our answer would be static (i.e. it couldn't adapt over time with your project).

    The fundamentals of compression (entropy) are constant, so I'd recommend you start from those "first principles". Even the assumption that this is the bottleneck, is unverifiable right now. I'd recommend prototyping a few different ideas to build a bigger picture. We'd likely be able to give more specific advice then, too.
