Answer 1

If you want to know which queries are sent to your db, you can use these two solutions :

• https://laravel.com/docs/5.5/database#listening-for-query-events
• https://github.com/barryvdh/laravel-debugbar

If you are looking for what does impact your performances, you can use these two instructions to target the right lines of your code :

$time = microtime(true); // we save the precise time in milliseconds
// some lines of code
dd(microtime(true) - $time); // prints the milliseconds spent since $time was saved
