Where to Find in Admin Menu

System > Tools > Performance and Opcache GUI

Installation

Method 1: Manual Installation

Copy to app/code, run setup, and compile as usual.

This Extension doesn't need static content generation - it uses CDN version of React JS. Install with flag --keep-generated.

Method 2: Composer Installation

composer require genaker/module-opcache

Post-Installation

php bin/magento module:enable Genaker_Opcache
php bin/magento setup:upgrade
php bin/magento cache:flush

Magento 2 OPcache Optimal Settings

The biggest Magento 2 performance issue is incorrect (default) PHP OPcache settings.

Production Web Server Settings

opcache.enable = 1
opcache.enable_cli = 0
opcache.memory_consumption = 556
opcache.max_accelerated_files = 1000000
opcache.validate_timestamps = 0
opcache.interned_strings_buffer = 64
opcache.max_wasted_percentage = 5
opcache.save_comments = 1
opcache.fast_shutdown = 1

CLI OPcache Settings

Separate CLI config file (e.g., /etc/php/8.1/cli/conf.d/10-opcache.ini):

zend_extension=opcache.so
opcache.memory_consumption=1000M
opcache.interned_strings_buffer=8
opcache.max_accelerated_files=10000000
opcache.validate_timestamps=1
opcache.enable_cli=1
opcache.file_cache=/tmp/
opcache.file_cache_only=0
opcache.file_cache_consistency_checks=1

Performance Benchmarking Features

PHP BogoMIPS Performance Measurement

Advanced PHP performance testing that measures actual Magento code execution speed.

Magento 2 is CPU-intensive due to framework design. Use the fastest CPU for optimal page rendering. If a 2GHz processor takes 3 seconds, a 3GHz processor will complete the same request in ~2 seconds.

Benchmark Reference Scores (lower is better):

• AWS C5.large: 0.032 (PHP 7.3.23)
• AWS R5.xlarge: 0.039 (PHP 7.2.34)
• AWS C8.xlarge: 0.029 (PHP 8.1 web), 0.066 (CLI - OPcache limitation)

HTTP Performance Testing

• Cached Testing: Measures Full Page Cache effectiveness
• Uncached Testing: Real logged-in user experience with cache-busting
• Random URL Testing: Dynamic product/category page performance
• Performance Comparison: Side-by-side analysis with improvement percentages

Cache Limitations Analysis

Educational warnings about Magento FPC behavior:

• FPC primarily benefits guest visitors only
• Logged-in customers typically bypass FPC
• Cache can be invalidated by content updates
• Search requests and category filters are rarely cached
• Focus on uncached performance for sustainable improvements

Advanced Configuration

Dependency Injection Configuration

Performance parameters can be customized via etc/di.xml:

<argument name="config" xsi:type="array">
    <item name="performance_iterations" xsi:type="number">3</item>
    <item name="http_performance_iterations" xsi:type="number">3</item>
    <item name="db_performance_iterations" xsi:type="number">3</item>
    <item name="collection_page_size" xsi:type="number">100</item>
</argument>

Performance Test Categories

• [PERFORMANCE BENCHMARK] - CPU, Memory, File I/O tests
• [HTTP PERFORMANCE] - Cached page performance
• [UNCACHED HTTP PERFORMANCE] - Real-world performance
• [CACHE PERFORMANCE COMPARISON] - Cached vs Uncached analysis
• [OPCACHE STATUS] - OPcache configuration analysis
• [PHP CONFIGURATION ANALYSIS] - PHP settings review
• [SECURITY ANALYSIS] - Security configuration assessment

What is BogoMIPS for Magento Servers?

MIPS = Millions of Instructions Per Second - measures Magento server computation speed.

BogoMips are Linus Torvalds' invention, adapted for Magento servers by Yehor Shytikov. Originally used in Linux kernel 0.99.11 (July 1993) for timing loop calibration.

"Bogo" = "bogus" (fake), indicating this is a practical rather than scientific measurement.

It's the most effective way to measure and compare Magento PHP code execution performance across different servers.
