Some of the tricks we used to speed up calls to our analytics API written in Python: played with asyncio, messed with SQLAlchemy, hacked deep in asyncpg, rewrote parts in Cython, found better data structures, replaced some pandas with pure numpy.
Most plugin based models load all assemblies into a single shared context. This is a common approach because it has better memory usage and startup performance. The history and rules of assembly loading in .NET is convoluted; its current status makes it difficult (and sometimes impossible) to load multiple different versions of the same assembly into a shared context.
