How to optimize work with MongoDB?

Question

MongoDB

There is a site with a medium-sized database (in active collections of 30,000 records), when the site reaches 300 people online, the site starts to load for a long time, 7-8 seconds each. The site is written in Laravel. Are there any options for some kind of optimization for the database itself and perhaps there are some tips for working with the database in laravel itself. Thanks in advance!
