You obviously have no idea of how a generational GC works.

Of course we have ideas, we actually think about the cause of performance
Do you want a 50+% speedup over the current time? Use a generational GC.
A 10% speedup? Make stack unwinding work across the managed->unmanaged
boundary with any compiler.
Another 5-10% speedup? Get the jit to produce better code (especially
better register allocation).
