Redis slower than MySQL

Question

I have two methods one of them queries the database and another one retrieves data from Redis cache.

public function aaa()
{
    for ($i = 0; $i < 1000; $i++) {
        $gl = DB::connection('webhesab')->table('gl_trans')
            ->where('memo_', 'LIKE', '%شعبه%')
            ->orWhere('account', '=', 111001)
            ->where('dimension2_id', '<>', 1)
            ->orWhere('person_id', '=', 0)
            ->where('dimension2_id', '<>', 1)
            ->orWhere('type_no', '<>', 50)
            ->limit(10)
            ->get();
    }
}

public function bbb()
{
    for ($i = 0; $i < 1000; $i++) {

        $gl = cache()->get('gl_trans');
    }
}

value of the cached object is exactly like query value.

But cache is so much slower than database query. roughly aaa longs 300 ms and bbb longs 1900 ms. Why? What is the problem?

Answer 1

you should post cache() implementation. without those, people can't help you explain why it's slow

there are some other points

1. redis shouldn't be that long even if you're not using pipeline or mget
2. you can use pipeline or mget to speed up redis even further.
