And promptly performance has just dropped by a magnitude or more.

Compiling various languages to Common Lisp (or some other host language) and running programs in its environment allows for safe near zero-cost IPC (through the use of object capabilities for maintaining isolation in memory) with no serialization overhead.

9p has a lot of such overhead.
