Download or clone the repository 2. Copy the files to `app/code/Amadeco/OpcacheGui/` 3. Run the following commands: ``` bin/magento module:enable Amadeco_OpcacheGui bin/magento setup:upgrade --keep-generated bin/magento cache:clean ``` Usage ----- [](#usage) ### Accessing the Dashboard [](#accessing-the-dashboard) Navigate to **System → React → PHP OpCache Dashboard** in your Magento Admin Panel. OPcache Optimization Guide -------------------------- [](#opcache-optimization-guide) ### Recommended PHP OPcache Settings for Magento 2 [](#recommended-php-opcache-settings-for-magento-2) ``` opcache.enable = 1 opcache.enable_cli = 0 opcache.memory_consumption = 1024 opcache.interned_strings_buffer = 128 opcache.max_accelerated_files = 60000 ; ; Production Mode ; opcache.validate_timestamps = 0 ; ; Development Mode ; ;opcache.validate_timestamps = 1 ;opcache.revalidate_freq = 10 ; opcache.save_comments = 1 opcache.enable_file_override = 0 ``` ### Technical Tips [](#technical-tips) #### Tip 1: Calculate Your Required Cache Size [](#tip-1-calculate-your-required-cache-size) ``` # Calculate the exact number of PHP files in your Magento codebase find . -type f -print | grep php | wc -l ``` Set `opcache.max_accelerated_files` to this number plus a 25% margin, rounded to the nearest higher prime number for optimal hash table performance. #### Tip 2: Implement Selective PHP Preloading [](#tip-2-implement-selective-php-preloading) For Magento 2, selective preloading is vastly more efficient than preloading all files: ``` // Example preload.php for Magento 2 function preload($path) { static $loaded = 0; if ($loaded >= 500) return; if (is_file($path) && preg_match("/\.php$/", $path)) { opcache_compile_file($path); $loaded++; } } // Only preload essential core files preload(__DIR__ . '/vendor/magento/framework/App/Bootstrap.php'); preload(__DIR__ . '/vendor/magento/framework/App/Http.php'); // Additional critical files... ``` References: - [Magento Community Issue #98](https://github.com/magento/community-features/issues/98#issuecomment-481635316) - [Example Implementation](https://github.com/MonogoPolska/monogo-m2-preload) #### Tip 3: Avoid JIT Compilation for Magento 2 [](#tip-3-avoid-jit-compilation-for-magento-2) JIT compilation causes segfaults with Magento 2 and provides minimal performance gains: ``` ; Disable JIT for Magento 2 opcache.jit_buffer_size = 0 opcache.jit = off ``` Reference: [Magento 2 PHP 8.2 JIT Performance Analysis](https://yegorshytikov.medium.com/magento-2-adobe-commerce-php-8-2-jit-performance-how-faster-is-magento-2-with-jit-876bdb8641a1) #### Tip 4: Blacklist Non-Essential Files [](#tip-4-blacklist-non-essential-files) Create an `opcache.blacklist` file to exclude test directories and rarely-used files: ``` /home/USER/public_html/vendor/*/Test/* /home/USER/public_html/vendor/*/tests/* /home/USER/public_html/dev/* /home/USER/public_html/setup/* ``` Then reference it in your php.ini or pool configuration: ``` opcache.blacklist_filename = /path/to/opcache.blacklist ``` #### Tip 5: Separate CLI and Web Process Configurations [](#tip-5-separate-cli-and-web-process-configurations) For optimal performance, maintain distinct OPcache configurations for CLI and web processes: **CLI Configuration** (`/etc/php/8.x/cli/php.ini`): ``` ; ; OpCache Config ; opcache.enable = 1 opcache.enable_cli = 1 opcache.memory_consumption = 512 opcache.interned_strings_buffer = 32 opcache.max_accelerated_files = 30000 opcache.max_wasted_percentage = 5 opcache.use_cwd = 1 ;

# Additional FastCGI settings... } # Admin requests location ~ ^/admin { fastcgi_pass unix:/var/run/php-fpm-magento-admin.sock; # Additional FastCGI settings... } ``` Benefits: - Better resource allocation based on specific needs - Isolation of admin processes from customer-facing frontend - Prevents admin-intensive tasks from impacting storefront performance - More efficient OPcache utilization for each context Configuration Location Matters ------------------------------ [](#configuration-location-matters) OPcache memory settings must be configured in php.ini rather than in PHP-FPM pool configuration files: 1. **Initialization Order**: OPcache initializes early in PHP's startup process, before pool configurations are processed 2. **Shared Memory Allocation**: Settings like `memory_consumption` define system-level allocations that must be consistent across PHP-FPM pools 3. **Global vs. Pool-specific Settings**: Some directives only work when set globally in php.ini Credits ------- [](#credits) - Based on [Genaker/Magento2OPcacheGUI](https://github.com/Genaker/Magento2OPcacheGUI) - Integrates with [amnuts/opcache-gui](https://github.com/amnuts/opcache-gui) - Enhanced by [Amadeco](https://www.amadeco.fr) License ------- [](#license) [MIT License](LICENSE.md) ### Health Score 34 — LowBetter than 77% of packages Maintenance58 Moderate activity, may be stable Popularity19 Limited adoption so far Community12 Small or concentrated contributor base Maturity40 Maturing project, gaining track record Bus Factor1 Top contributor holds 56.7% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
