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>

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.
