Performance & Caching

Optimize performance for sites with thousands of files.

Overview

PraisonPressGit includes intelligent caching and indexing systems to handle sites of any size efficiently.

Caching System

WordPress Transients

File content is cached using WordPress transients:

// Configure cache TTL
add_filter('praison_cache_ttl', function($ttl, $post_type) {
    if ($post_type === 'lyrics') {
        return 7200; // 2 hours for lyrics
    }
    return $ttl;
}, 10, 2);

Cache Invalidation

Cache automatically invalidates when: - Files are modified - Admin clears cache manually - TTL expires

Clear Cache

Admin Dashboard: Click "Clear Cache" in the PraisonPress dashboard

WP-CLI:

wp cache flush
wp transient delete --all

Index System

For large sites (1,000+ files), enable the index system:

Build Index

# Generate index file
php wp-content/plugins/praisonpressgit/scripts/build-index.php

Index Benefits

Site Size	Without Index	With Index
< 1,000	0.5s	0.2s
1,000 - 10,000	2-5s	0.2s
10,000 - 100,000	10-30s	0.5-2s

Scaling Guide

Small Sites (< 1,000 files)

Performance: ~0.5s load time
Memory: ~50MB
Cache: WordPress transients

Medium Sites (1,000 - 10,000 files)

Performance: ~0.2s load time (5x faster)
Memory: ~80MB
Cache: Transients + Object cache
Index: Recommended

Large Sites (10,000 - 100,000 files)

Performance: ~0.5-2s load time (50x faster)
Memory: ~150MB
Cache: Redis/Memcached required
Index: Required

Object Cache

For best performance, use Redis:

// wp-config.php
define('WP_REDIS_HOST', 'redis-service');
define('WP_REDIS_PORT', 6379);

Install Redis Object Cache plugin:

wp plugin install redis-cache --activate
