README

this extension requires Redis Magento Builtin cache enabled and php_redis php extension installed. The phpredis extension provides a native PHP API for communicating with the Redis key-value store.

Tested With: 2.4.7 Magento version

#RHEL / CentOS
#Installation of the php-pecl-redis package, from the EPEL repository:

yum install php-pecl-redis

Cloud Flare CDN FPC Cache Microservice Layer

Works great together with this Cloud Flare Worker FPC cache Layer: https://github.com/Genaker/CloudFlare_FPC_Worker

The Idea behind this Magento 2 FPC performance extension

When I developed a Shopware 6-based website I noticed fast sub 1ms performance of the FPC cache. I checked the code and it amazed me. It is simple and made the right PHP way! Symfony Http cache! You don't need Varnish to run your FPC cache fast. You need just fast code without reusing the Magento 2 junk core framework.

Installation

Nginx

fastcgi_param PHP_VALUE "auto_prepend_file=/var/www/html/magento/app/code/Mage/FPC/FPC.php";

/var/www/html/magento/app/ shuld be changet to your magento path

or

add it as a first line to app/bootstrap.php or pub/index.php

Also if you are using composer to install this stuff your path will be something like : ../vendor/mage/fpc/src/Mage/FPC.php

Installation into the app folder is preferable. It is not a useless library. It is a part of your business to keep your site FAST.

require "../app/code/Mage/FPC.php";

Also, this extension will work without this additional interaction (just install and forget) but it will be slower because it will load all Magento 2 via autoloader.

or do next:

composer require mage/fpc
bin/magento setup:upgrade
bin/magento fpc:deploy

Performance

FPC generation time is 0.000481128 second.

Test

Test Magento Headers:

NodeJS implementation

npm install ioredis node-cache dotenv
or nmp install
node FPC.js

Replace Nginx:

location / {
    try_files $uri $uri/ /index.php$is_args$args;
}

With:

# Try Node.js first, fallback to static files, then PHP
location / {
    # Try serving from Node.js first
    proxy_pass http://127.0.0.1:3001;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

    # If Node.js fails, fallback to static files and then PHP
    error_page 406 502 504 = @fallback;
}

# Fallback to Static Files or PHP if Node.js Fails
location @fallback {
    try_files $uri $uri/ /index.php$is_args$args;
}

Understanding Stale-While-Revalidate

The stale-while-revalidate caching strategy is designed to minimize latency by serving cached content immediately, even if it’s slightly outdated, while simultaneously updating the cache with fresh data in the background. This approach ensures that users receive a quick response and the cache remains up-to-date without blocking the main request flow.
