IS there documentation anywhere on how to process large numbers of characters, or just large meshes, etc. are there best practices rules, specifically for objects, is the memory released when an object is deleted, what about moving scene to scene and memory management or bringing in another .blend file. Any improvements from solid state disks?

My project involves a lot of characters, large amounts of text as objects, the game engine, python, animation, and storing large amounts of data in sqlite. I have been working for ahwile (couple years) on using blender to alter the current medium of education delivery.
I beleive the concept of using Blender in education is terrible underutilized.
For that matter all multimedia is underutilized!
thanks

Hello
"Performance"? Bad!
Use other Game Engine!
Anyway, if you work alone, Blender is, most probably, enough for the task!
Bye

The prerequisite is that the game engine be free. regardless an understanding of memory and other resource management would be helpfull.
