command php artisan optimize not defined in Lumen 5
<p>I am using Lumen 5.1.6 , Is there any way to improve its performance? my API is taking long time (around 9000 ms) to response.I searched and found <code>php artisan optimize</code> and <code>php artisan route:cache</code> commands but these are not available in Lumen. Can anybody please help me to reduce API response time ? Thanks much!!!</p>
