context --help | grep jit

  --jit    use luajittex with jit turned off (only use the faster virtual machine)
  --jiton  use luajittex with jit turned on (in most cases not faster, even slower)

I've never come across a real world document where --jiton was
faster than --jit, so just stick with --jit.
