Predis set method is slow and slow, what is the reason?

Here is my code:

  Redis) {$cfg = [' scheme ' = + env (' Redis_scheme ', ' TCP '), ' host ' = env (' RE            Dis_host ', ' 127.0.0.1 '), ' port ' = env (' Redis_port ', 6379)];        $this->redis = new \predis\client ($CFG);    }}/** * Close the session * @since 5.4.0 */Public Function Close () {return true;    }/** * Destroy a session * @return Boolean * @since 5.4.0 */Public Function Destroy ($session _id)        {$this->connect ();        $this->redis->del ($session _id);    return true;    }/** * Cleanup old Sessions * @return Boolean * @since 5.4.0 */Public Function GC ($MAXLIFETIME)    {return true;        }/** * Initialize session * @since 5.4.0 */Public Function open ($save _path, $sessionName) {    return true; }/** * Read session data * @return String * @since 5.4.0 */Public function Read ($session _id) {$this->connect ();            if ($this->redis->exists ($session _id)) {$value = $this->redis->get ($session _id); Return $value?        ($value): ';            } else {$expire = Configure (' Ymf.Account.expire ');            $this->redis->setex ($session _id, $expire, ");        Return ';    } return '; }/** * Write session Data * @return Boolean * @since 5.4.0 */Public Function Write ($session _id, $s        Essiondata) {$this->connect (); File_put_contents (__dir__. '/.. /..        /write.log ', "write {$sessionData}\r\n", file_append);        if ($this->redis->set ("Flf", "HFL")) {return true;        } else {return false; }    }}

Troubleshooting will only, find this $this->redis->set method particularly slow, what reason ....
