Parse server with Fastify?

I’ve seen a test where fastify outperformed express by 27% in 10 trials, which made me wonder if I can run parse server with fastify. Though this appears not to be possible, since parse server was designed for express. However theres fastify/express middleware that allows using express methods with fastify, which can theoretically make fastify compatible with parse server but im wondering if using middleware would negate performance superiority of fastify? How do you think?
