Optimize Shapes and vector layers
Currently the biggest bottleneck or noticeable speed degredation for me after getting a CPU with more cores and a lower clockspeed has been shape layers and vectors. If I have a comp with lets say 100 small shape circles, the FPS in After Effects drops to such a low level it is hard to even work. Since things are being optimized in After Effects and tasks are being moved to the GPU, this is one area of the program I would really like to be improved. Shapes and vector layers are very commonly used, so it shouldn't be such a huge bottleneck with modern hardware.
The latest (November 2019) release of After Effects includes significant optimizations for shape layer performance — particularly when snapping, and with complex shape-based projects. Please let us know if you see an improvement.

I have 12 core CPU, and gtx 980 ti, how it comes to character animation and working with a large number of layers, I want to ask the developers, do they even know what optimization is?

Seconded, shape layers unfortunately add so much lag to my compositions that I use them only as a last resort, which is a shame since i love many of the features they bring to the table.
