How to speed up LeftJOIN LARAVEL?

Question

SQL

There is a request like this:

AllItem::leftJoin('items',function($join) use ($case){
            $join->on('items.classid','=','all_items.classid');
            $join->where('items.case_id','=',$case->id);
        })->orderBy('items.created_at','desc')->select('all_items.*')->paginate(10);

Now its execution time takes about 30 seconds (sometimes longer).

There are ~80 thousand records in the `all_items` table, ~1500 records in the `items` table.

Is it possible to speed up the query execution time?
