I don't think it's about getting 1ms execution time: It's more like having 300ms vs 301ms execution time be very similar in cost (or however the rounding worked).
The firecracker microvm says startup time is under 125ms, but I have not personally done any benchmarking, though my employer does use firecracker for hosting our CI builders.
