нужно найти лишний код,который нагружает сервер. PHP

namespace NV;

use pocketmine\event\Listener;
use pocketmine\entity\Entity;
use pocketmine\event\player\PlayerJoinEvent;
use pocketmine\command\Command;
use pocketmine\command\CommandSender;
use pocketmine\command\ConsoleCommandSender;
use pocketmine\Player;
use pocketmine\plugin\PluginBase;
use pocketmine\utils\Config;

class LDC extends PluginBase implements Listener {
public $key, $Perms;

public function onEnable() {
$this->getServer()->getPluginManager()->registerEvents($this, $this);

if(!is_dir($this->getDataFolder())) {
mkdir($this->getDataFolder(), 0777 ,true);
$this->saveDefaultConfig();
}
$this->key = new Config($this->getDataFolder()."keys.yml", Config::YAML);

$this->PurePerms = $this->getServer()->getPluginManager()->getPlugin("PurePerms");

}```
