How much will load the server every second ajax requests?

Question

JavaScript

Will there be a big difference (load on the server) if instead of using websocket, I send ajax requests from the user every second. Or are Ajax requests harder to accept by the server?)
This request is needed only for one feature, and you don’t want to write a websocket server for it.
What will be more rational? Write a websocket for just one feature? Or send ajax requests every second?

Answer 1

Without keepAlive, it will take a lot of time to connect, and ssl handshakes can generally take a long time.
With keepAlive, as far as I understand, each server user will select a worker exclusively for himself, which limits the number of simultaneous users.
