La consulta de registros activos de Codeigniter toma demasiado tiempo para cargar datos de la base de datos

Use la paginación, esta es la mejor manera de usarlo

créelos para que funcionen en el modelo

Modelo

public function get_count($table){
        return $this->db->count_all_results($table);
    }

    public function get_all_userdata($table, $where, $limit, $start){
        $query = $this->db->get_where($table, $where, $limit, $start);
        $data = $query->result_array();
        return $data;
    }
