🚀 Performance & Optimization

⚡ Processing Benchmarks

File Type	Size	Processing Time	Memory Usage	Output Quality
JPEG (5MP)	2.1MB	~1.8s	~45MB	Excellent
PNG Screenshot	1.8MB	~2.2s	~55MB	Lossless
WebP Conversion	850KB	~1.5s	~35MB	Optimized
Batch (10 images)	25MB total	~15.2s	~140MB	Mixed formats

🔧 Performance Tuning

Memory Optimization

// For large image files
ini_set('memory_limit', '512M');
set_time_limit(300);

// Efficient batch processing
$batchSize = 5; // Process 5 files at a time
$chunks = array_chunk($files, $batchSize);

foreach ($chunks as $chunk) {
    $optimizer->optimizeBatch($chunk, $options);
    gc_collect_cycles(); // Free memory
}

Caching Strategy

// Enable result caching
$cacheKey = md5($filepath . filemtime($filepath) . json_encode($options));
$cached = $cache->get($cacheKey);

if (!$cached) {
    $result = $optimizer->optimizeImage($file, $options);
    $cache->set($cacheKey, $result, 3600); // 1 hour cache
    return $result;
}

Recommended .htaccess

# Prevent direct access to sensitive files
<Files "*.php">
    <RequireAll>
        Require all denied
        Require local
    </RequireAll>
</Files>

# Allow only specific entry points
<Files "index.php">
    Require all granted
</Files>
<Files "process.php">
    Require all granted  
</Files>
<Files "download.php">
    Require all granted
</Files>

# Prevent execution in upload directories
<Directory "uploads/">
    php_flag engine off
    AddHandler cgi-script .php .pl .py .jsp .asp .sh .cgi
    Options -ExecCGI
</Directory>

🐛 Troubleshooting

❌ Common Issues

Large Files Not Processing

# Check file size limits
php -r "echo 'Max upload: ' . ini_get('upload_max_filesize');"
php -r "echo 'Max post: ' . ini_get('post_max_size');"

# Increase limits in .htaccess or php.ini
upload_max_filesize = 100M
post_max_size = 500M
max_execution_time = 300
memory_limit = 512M

AVIF Generation Failing

# Check AVIF support
php -r "echo function_exists('imageavif') ? 'AVIF supported' : 'Install ImageMagick or upgrade PHP';"

# For ImageMagick AVIF support
sudo apt-get install libheif-dev
# Recompile ImageMagick with HEIF support

WebP Not Working

# Check WebP support in GD
php -r "echo (gd_info()['WebP Support'] ?? false) ? 'WebP supported' : 'Upgrade GD extension';"

Large File Timeouts

# Increase limits in .htaccess
php_value max_execution_time 600
php_value memory_limit 1G
php_value upload_max_filesize 200M

Permission Errors

# Fix directory permissions
sudo chown -R www-data:www-data uploads/ optimized/ temp/ logs/
chmod 755 uploads/ optimized/ temp/ logs/
chmod 644 .htaccess

📝 Error Codes

Code	Issue	Solution
400	Unsupported format	Check supported formats list
413	File too large	Increase upload_max_filesize
422	Processing failed	Check ImageMagick installation
500	Processing failed	Check logs/, increase memory
503	Server overloaded	Reduce batch size, upgrade server
