Fast Character Rigging using bones and tools - NATIVELY!

Yes, it's my dream that AE would work quickly with character animation. I like AE and its built-in tools and third-party plugins so much that I just don't want to learn other programs. But unfortunately in AE I do not know why, but vector layers are processed much longer than anywhere else. Also the presence of expressions slow down the program a lot. Even if you just have an expression that triggers once and the value of the expression does not change in time, still as I understand AE checks every frame in the composition because of what performance suffers.
