为什么我使用laravel的查询非常慢

Question

1.I use laravel version 5.6. 2.Database aurora MYSQL (AWS).

I query it's use approximately more than 1s for first query. In category table had just 5 rows.

Array
(
    [0] => Array
        (
            [query] => select * from `admins`
            [bindings] => Array
                (
                )

            [time] => 1716.88
        )

    [1] => Array
        (
            [query] => select * from `category`
            [bindings] => Array
                (
                )

            [time] => 267.61
        )

)

First time use more than 1s always.

Array (
    [0] => Array
        (
            [query] => select * from `category`
            [bindings] => Array
                (
                )

            [time] => 1379.56
        )

    [1] => Array
        (
            [query] => select * from `admins`
            [bindings] => Array
                (
                )

            [time] => 628.41
        )

)

use this

 $rows = Category::get(); 
 $rows1 = Admins::get();
 print_r(DB::getQueryLog());

How to fixing? Thank you.
