Performance

EduLab LMS is optimised out of the box for shared hosting. This page covers the built-in caching layers and additional steps you can take to maximise speed.

Built-in Caching

Data	Cache Key	TTL	Invalidated When
Theme settings (all)	options	Forever	Any setting is saved
Active theme list	lms_themes	10 min	— (auto-expire)
Geolocation per IP	geo_<ip_hash>	24 hours	— (auto-expire)
Application config state	lms_app_cfg	2 hours	License is activated / removed
Language list	languages singleton	Per-request	—

Cache is tenant-aware when the SaaS module is active — the tenancy bootstrapper automatically prefixes cache keys per tenant.

Recommended: Enable Cache Driver

By default Laravel uses the file cache driver. Switch to database or redis for better performance:

Database cache (works on all shared hosts):

php artisan cache:table
php artisan migrate

Then in .env:

CACHE_STORE=database

Redis (recommended for VPS/dedicated):

CACHE_STORE=redis
REDIS_HOST=127.0.0.1
REDIS_PORT=6379

Artisan Optimize Commands

Run these after each update or configuration change:

php artisan optimize        # Cache config + routes + views
php artisan config:cache    # Cache config only
php artisan route:cache     # Cache routes only
php artisan view:cache      # Pre-compile all Blade views

These commands are also available via Admin → Dashboard → Optimize Cache.

To clear all caches:

php artisan optimize:clear

Database Indexes

Version 3.0 ships with a migration that adds indexes on the most frequently queried columns:

• courses: slug, status, category_id
• categories: slug
• purchase_details: type
• blogs: slug
• theme_settings: key
• users: guard

Run php artisan migrate after updating to apply them.

Shared Hosting Tips

• Enable OPcache in your PHP configuration — this is the single biggest win on shared hosting.
• Set APP_DEBUG=false in .env on live sites.
• Avoid using the sync queue driver on slow connections — use database queue instead.
• Schedule the Laravel scheduler via a single cron entry:

* * * * * cd /path/to/project && php artisan schedule:run >> /dev/null 2>&1
