Optimizing WordPress Performance on Your Breeze

Introduction

WordPress is the most popular CMS, but it requires optimization to run well under traffic. These techniques can make your WordPress site load in under 2 seconds.

Install a Caching Plugin

Caching plugins serve pre-generated HTML instead of running PHP for every request:

• WP Super Cache — simple, reliable, by Automattic
• W3 Total Cache — comprehensive with CDN integration
• LiteSpeed Cache — best if running OpenLiteSpeed

Object Caching with Redis

# Install Redis
sudo apt install -y redis-server php-redis
sudo systemctl restart php8.2-fpm

# Install Redis Object Cache plugin in WordPress
# Settings → Redis → Enable Object Cache

Image Optimization

• Use WebP format (30% smaller than JPEG)
• Lazy load images below the fold
• Use the srcset attribute for responsive images

Database Optimization

# Clean up from MySQL CLI
DELETE FROM wp_posts WHERE post_type = 'revision';
DELETE FROM wp_options WHERE option_name LIKE '_transient_%';
OPTIMIZE TABLE wp_posts, wp_postmeta, wp_options;

PHP Configuration

# In php.ini
opcache.enable=1
opcache.memory_consumption=128
memory_limit=256M

Performance Checklist

• Enable page caching
• Enable object caching (Redis)
• Minimize plugins (each adds overhead)
• Use a lightweight theme
• Enable Gzip compression
• Set browser cache headers
