How does the overhead of creating a new process for every request compare to language specific runtimes.

I realise it will be more, since it adds flexibility, just curious how much.

Good question - it depends entirely on the disk storage, RAM generation & speed and CPU. Golang and Python are fastest. I am sure it could be further optimized for a given combination.

Tested on a Type 3 Packet Bare Metal host with latest Docker Swarm. The NodeJS example called NodeInfo comes back in around 0.1s / 100ms for a round-trip. A bash built-in (cat) is 0.015s / 15ms. Golang sample markdown function - 0.024s / 24ms.
