NodeJS or PHP 7.1 for proxy?

Question

PHP

I choose the language for the microservice.
DB - mongodb
The essence of the service: proxying JSON requests, saving the request and adding the id of the saved request to the response.
Algorithm:

• to accept
  
• request from A
  
• redirect to B
  
• generate UUID
  
• get a response from
  
• add a UUID to the response and return response A. the connection can be closed
  
• save request and response body
  
• some other operations
  

It is important to minimize the time for which A will receive a response and that could process a bunch of requests
. What should I choose php-fpm (php7.1) + nginx or nodejs + nginx in this case?
m.b. other options? like nodejs without nginx?
On synthetics (and here are quite synthetic tasks), it turns out that the node is better?

Answer 1

IMHO nginx+nodejs

Answer 2

nginx without everything, for example, you can try.
Just make a uuid generator or google it.

Answer 3

In order of processing speed:
1. easier and faster - write a microservice in C and run it as a daemon.
2.

like nodejs without nginx? On synthetics (and here are quite synthetic tasks), it turns out that the node is better?

or this option: a clean node without layers.
