    All else being equal, v8 isolates should be lower latency than firecracker.

    As they mention, the v8 latency was because the v8 runtime was hosted externally.

    Firecracker has better security model.

    This old thread[0] with kentonv author of Cloudflare's workers platform covers some of the differences.
