3.2 Performance Tuning Guide (PERFORMANCE.md)

# ⚡ Performance Tuning Guide

## Auto-Tuning Overview

EasyInstall automatically tunes your server based on:

| Parameter | Auto-Tuned By | Manual Override |
|-----------|---------------|-----------------|
| PHP-FPM children | ✓ (CPU/RAM) | `/etc/php/*/fpm/pool.d/www.conf` |
| MySQL buffer pool | ✓ (RAM) | `/etc/mysql/mariadb.conf.d/99-wordpress.cnf` |
| Redis maxmemory | ✓ (RAM) | `/etc/redis/redis.conf` |
| Nginx connections | ✓ (RAM) | `/etc/nginx/nginx.conf` |
| Kernel parameters | ✓ | `/etc/sysctl.d/99-wordpress.conf` |

## Manual Tuning Guide

### PHP-FPM Tuning

```ini
# /etc/php/8.3/fpm/pool.d/www.conf

# Dynamic scaling (auto-tuned by EasyInstall)
pm = dynamic
pm.max_children = 40        # Based on RAM (40 for 4GB)
pm.start_servers = 8        # 20% of max_children
pm.min_spare_servers = 4    # 10% of max_children
pm.max_spare_servers = 12   # 30% of max_children

# Process management
pm.max_requests = 10000     # Restart after X requests (prevents memory leaks)
pm.status_path = /status    # Enable status page

# Timeouts
request_terminate_timeout = 300s
request_slowlog_timeout = 5s
slowlog = /var/log/php-fpm-slow.log

# Socket
listen = /run/php/php8.3-fpm.sock
listen.backlog = 65535

Calculation Formulas:

max_children = (Total RAM - MySQL RAM - Redis RAM - 200MB) / (PHP Memory Limit)
Example: (4096MB - 512MB - 256MB - 200MB) / 64MB = 48 children

---

MySQL Tuning

# /etc/mysql/mariadb.conf.d/99-wordpress.cnf

# InnoDB (80% of RAM for dedicated DB servers)
innodb_buffer_pool_size = 1G        # 25% of RAM for mixed workloads
innodb_log_file_size = 512M
innodb_log_buffer_size = 16M

# Connection pooling
max_connections = 500
thread_cache_size = 256

# Query cache (disabled in MySQL 8+, but enable for MariaDB)
query_cache_type = 1
query_cache_size = 128M
query_cache_limit = 2M

# Slow query logging
slow_query_log = 1
long_query_time = 2
log_queries_not_using_indexes = 1

# Write optimization
innodb_flush_log_at_trx_commit = 2
innodb_flush_method = O_DIRECT
innodb_file_per_table = 1

---

Redis Tuning

# /etc/redis/redis.conf

# Memory
maxmemory 512mb
maxmemory-policy allkeys-lru

# Persistence (disable for cache-only)
save ""                    # Disable RDB snapshots
appendonly no              # Disable AOF

# Performance
tcp-backlog 65535
timeout 0
tcp-keepalive 300

# Latency
hz 20                       # Background tasks frequency
dynamic-hz yes

# Memory optimization
maxmemory-samples 10        # LRU samples
activedefrag yes            # Auto-defragmentation

Troubleshooting Performance Issues

High CPU Usage

# Find CPU-intensive processes
top -c

# Check PHP-FPM workers
ps aux | grep php-fpm | wc -l

# Check slow queries
mysql -e "SELECT * FROM mysql.slow_log ORDER BY start_time DESC LIMIT 10;"

# Debug WordPress queries
wp db query "SHOW FULL PROCESSLIST;" --allow-root

Memory Exhaustion

# Check memory usage
free -h
ps aux --sort=-%mem | head -20

# Restart PHP-FPM (zero downtime)
systemctl reload php8.3-fpm

# Clear Redis cache
redis-cli FLUSHALL

# Check Redis memory
redis-cli INFO memory

Slow Page Load

# Measure TTFB
curl -w "@curl-format.txt" -o /dev/null -s https://mysite.com/

# Check nginx cache
grep X-Cache /var/log/nginx/mysite.com.access.log

# Test database queries
wp db query "SELECT * FROM wp_options WHERE autoload='yes' AND LENGTH(option_value) > 10000;" --allow-root
