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.

Compatibility
Each Magento release line is installed on its supported PHP versions, then the module is built (DI compilation + static-content deploy) and its unit and integration suites are run. The matrix shows the lines and PHP versions the module is confirmed to install and run on. Code-quality results further down (phpstan, phpcs, …) are reported separately and never affect compatibility.
Code Quality
Advisory checks against the module's source. Static analysis runs once across the whole module; PHPStan re-runs per Magento + PHP version because resolvable symbols differ between releases. These NEVER affect the Compatibility badge — a phpcs finding can't make a module incompatible.
Static analysis
Coding standards (phpcs), mess detection (phpmd), copy-pasted code (cpd), PHP cross-version compatibility, composer.json validity. Each runs once for the whole module.
| Tool | Status | Findings | Summary |
|---|---|---|---|
| PHPCS | Fail | 340 | 20 errors, 320 warnings (ruleset: Magento2) — 61 auto-fixable with phpcbf |
| PHPMD | Warning | 59 | 59 rule violations (CyclomaticComplexity:12, UnusedLocalVariable:12, NPathComplexity:11, ExcessiveMethodLength:8, MissingImport:7) |
| Cpd | Warning | 1 | 1 duplicated chunk spanning 42 total lines (min-lines=5, min-tokens=70) |
| Composer validate | Pass | 0 |
PHPStan
Type-checks the module's PHP against a real Magento install at the configured gate level. Re-runs per Magento and PHP version because resolvable symbols differ between releases. Cell → details modal.
Tests
Unit and integration suites, run for each applicable Magento and PHP version. A test failure speaks to the module's behaviour, not its compatibility with a Magento line, so it is reported here separately and never reddens the compatibility matrix.
Unit tests
| Magento | PHP 8.2 | PHP 8.3 | PHP 8.4 | PHP 8.5 |
|---|---|---|---|---|
| 2.4.7 | N/A | N/A | ||
| 2.4.8 | N/A | N/A | ||
| 2.4.9 | N/A | N/A |
Integration tests
| Magento | PHP 8.2 | PHP 8.3 | PHP 8.4 | PHP 8.5 |
|---|---|---|---|---|
| 2.4.7 | N/A | N/A | ||
| 2.4.8 | N/A | N/A | ||
| 2.4.9 | N/A | N/A |
Security
Security checks run directly against the module: an audit of its declared dependencies for known vulnerabilities (composer audit) and a scan of its source for malware and web-shell signatures. Each runs once. A malware detection fails the version outright.
