There's a JIT, so running the same thing more than once makes it faster: ~ # time hello Hello, world! real 0m 1.89s user 0m 0.67s sys 0m 1.14s ~ #

There's a JIT, so running the same thing more than once makes it faster: ~ # time hello Hello, world! real 0m 1.89s user 0m 0.67s sys 0m 1.14s ~ # time hello Hello, world! real 0m 0.97s user 0m 0.36s sys 0m 0.55s This would to me imply an obvious route of pre-warming the resumed image with your program. Or going all-in and natively compiling to wasm, but that's a much bigger lift.
