Cold starts for the VM are only part of the problem. If you're on a JITed runtime, a cold start also means compilation and optimization. It would be nice if they had ways to cache the JITed machine code so they could start back up with it already compiled and optimized.

Modern lambdas can be paused for 4+ hours before experiencing cold starts (depending on a lot of variables).

AWS is making continual improvements in this area.
