Laravel’s primary deployment optimization command is php artisan optimize, which caches configuration, events, routes, and views. The granular commands are config:cache, event:cache, route:cache, and view:cache; optimize:clear removes generated optimization caches when configuration or deployment troubleshooting requires it.

Run these as part of a repeatable deployment process after the correct environment configuration is present. With configuration cached, env should only be called from configuration files. After deployment, reload or restart long-running queue workers, Horizon, Reverb, and Octane so they use the new code. Optimization commands complement proper OPcache, database indexing, asset builds, and observability.
