Nginx Unit + PHP seems to handedly out-perform Nginx + php-fpm[1][2][3]. Also, Docker environments running PHP via Nginx Unit will no longer need separate cont

  You don't need separate containers to run nginx and php-fpm.

    Are you implying that docker containers don't run a unikernel that can only run one application at a time? /s

      I am happily running Nginx + supervisord + several Python apps in a single Docker container.

        Not gonna lie I tend to use docker like minimal disposable VMs from time to time lol
  • kobalsky 3y ago
    does it involve running supervisor inside the container? that’s fine but it’s definitely not kosher. in my experience those are the ones that kick and scream when they don’t start as root.

      php-fpm & nginx -g "daemon off;"

        this is … not how I’d do it

    I too would like to see a properly configured php+php-fpm container benchmark. There's a lot of overhead when you link by http instead of a unix socket, in the same container.
    • e12e 3y ago
      Technically, you should be able to share a domain socket via a shared volume too (between an "app" and "web" container) - as with postgres: https://github.com/sameersbn/docker-postgresql/issues/30#issuecomment-401520497 https://github.com/sameersbn/docker-postgresql/issues/30#iss... Curious about benchmarks and tests of TCP vs Unix domain sockets between docker containers.

        Another example is API Platform's docker setup: Volume config: https://github.com/api-platform/api-platform/blob/main/docker-compose.yml#L41 https://github.com/api-platform/api-platform/blob/main/docke... Caddy config: https://github.com/api-platform/api-platform/blob/main/api/docker/caddy/Caddyfile#L47 https://github.com/api-platform/api-platform/blob/main/api/d... php-fpm config: https://github.com/api-platform/api-platform/blob/main/api/docker/php/php-fpm.d/zz-docker.conf#L6 https://github.com/api-platform/api-platform/blob/main/api/d... I'm also curious on the performance differences between containers.

        I found a simple comparison from 2014 - which shows Unix domain sockets to have a 2-3x advantage over localhost TCP: "Unix Domain Sockets vs Loopback TCP Sockets" https://nicisdigital.wordpress.com/2014/03/03/unix-domain-sockets-vs-loopback-tcp-sockets/ https://nicisdigital.wordpress.com/2014/03/03/unix-domain-so...

  Those benchmark outcomes are ridiculously in nginx-unit’s favor over php-fpm, way more than I would have believed was possible. What is php-fpm doing architecturally that is so different to warrant such poor relative performance?
  • pbowyer 3y ago
    You see similar performance improvements in bencharmarks of Litespeed & PHP LSAPI [1]. Unfortunately said benchmarks are usually done by the software company making said webserver, so have to be taken with a pinch of salt. 1. https://www.litespeedtech.com/open-source/litespeed-sapi/php https://www.litespeedtech.com/open-source/litespeed-sapi/php

  Two questions: 1. Does Unit + PHP doing the typical “initialize & teardown” that PHP is know for? Or is Unit persisting the initialization/setup, hence why it’s achieving the way faster results? 2. How is Unit/PHP architecturally different than NGX-PHP (an event loop)? https://github.com/rryqszq4/ngx-php https://github.com/rryqszq4/ngx-php

    PHP’s had an opcache and jit for several versions now. Combined with preload options, this means startup time is negligible.
