Клас кэширования страниц, конфигов и объектов

[dem66]

Доброго времени суток.
Возникла потребность в кешировании, как можно упростить данных клас и ускорить его работу?

PHP код:

<?php
Class DF_cache{

    public static function Create(){
        static $instance;

        if($instance==null){
            $instance = new DF_cache;
        }
        return $instance;
    }

    private $_data;
    public function SetData($data){
        $this->_data = $data;
        return $this;
    }

        private $_resource;
    public function SetResource($resource){
        $this->_resource = $resource;
        return $this;
    }

    private $_type;
    public function SetType($type){
        $this->_type = $type;
        return $this;
    }

    private $_name;
    public function SetName($name){
        $this->_name = $name;
        return $this;
    }
    private $_Serialize = 'true';
    public function Serialize($stat = 'true'){
        $this->_Serialize = $stat;
        return $this;
    }

    public function Get(){
            $data = NULL;
        Switch($this->_resource)
        {
            case('Page'):
                 $file = CACHE_PATH.'/page_'.$this->_name.'.tmp';
                if($this->Check($file)==1){
                    $data = file_get_contents($file);
                }
            break;
            case('Config'):
                Switch($this->_type)
                {
                case('Session'):
                    if(isset($_SESSION[$this->_name])){
                        $data = $_SESSION[$this->_name];
                    }
                break;
                case('File'):
                    $file = CACHE_PATH.'/config_'.$this->_name.'.tmp';
                    if($this->Check($file)==1){
                        switch($this->_Serialize){
                            case('true'):
                                $data = unserialize(file_get_contents($file));
                            break;
                            case('false'):
                                $data = file_get_contents($file);
                            break;
                        }
                    }
               break;
               }
           break;
           case('Object');
                 $file = CACHE_PATH.'/object_'.$this->_name.'.tmp';
                if($this->Check($file)==1){
                    switch($this->_Serialize){
                        case('true'):
                            $data = unserialize(file_get_contents($file));
                        break;
                        case('false'):
                            $data = file_get_contents($file);
                        break;
                    }
                }
            break;
        }
                $this->_name = NULL;
                $this->_data = NULL;
                $this->_type = NULL;
                $this->_resource = NULL;

                return $data;
    }

    public function Save(){
            $data = NULL;
        Switch($this->_resource)
        {
            case('Page'):
                file_put_contents(CACHE_PATH.'/page_'.$this->_name.'.tmp', $this->_data);
            break;
            case('Config'):
                Switch($this->_type)
                {
                case('Session'):
                    $_SESSION[$this->_name] = $this->_data;
                break;
                case('File'):
                    file_put_contents(CACHE_PATH.'/config_'.$this->_name.'.tmp', serialize($this->_data));
                break;
               }
            break;
            case('Object');
                file_put_contents(CACHE_PATH.'/object_'.$this->_name.'.tmp', serialize($this->_data));
            break;
        }
                $this->_name = NULL;
                $this->_data = NULL;
                $this->_type = NULL;
                $this->_resource = NULL;
                
                return $data;
    }
    private $_time;
    public function TimeOut($time){
            $this->_time = $time;
            return $this;
    }
    private function Check($file){
            if(file_exists($file)){
                         $mtime = filemtime($file);
                         $time = time()-$mtime;
                         $minut = $time/60;
                         
                         $timeout = $this->_time;

                         if($minut>=$timeout){
                             unlink($file);
                             return 2;
                         }else{
                             return 1;
                         }
                         return 1;
            }else{
                return 2;
            }
        }

}

Пример использования:

PHP код:

$cache = DF_cache::Create();
$cache->SetResource('Object');
$cache->SetName("page1");
$result = $cache->Get();
if(empty($result)){
  result = ...// тут какой то код на получение данных
  $this->cache->SetResource('Object');
  $this->cache->SetName("page1");
  $this->cache->SetData($result);
  $this->cache->Save();
} 


Данный клас работает очень долго, около 0.2 с ((((
