Лак: не отличается по характеристикам

Я установил лак на свой сервер centos, но у меня больше не было производительности, мой сайт загружался за 7 секунд до его установки, а после установки он все еще 7 секунд,
в чем проблема?

sub vcl_recv {

    remove req.http.X-Forwarded-For;
    set req.http.X-Forwarded-For = client.ip;

    if(req.http.cookie ~ "userID" || req.url ~ "^/administrator" || req.url ~ "^/component/banners" || req.request == "POST") {
        return (pass);
    }

    if(req.http.x-logged-in == "False" && req.request != "POST"){
        unset req.http.cookie;
    }

    if (req.http.Accept-Encoding) {
      if (req.url ~ "\.(jpg|jpeg|png|gif|gz|tgz|bz2|tbz|mp3|ogg|swf)$") {
        remove req.http.Accept-Encoding;
      } elsif (req.http.Accept-Encoding ~ "gzip") {
        set req.http.Accept-Encoding = "gzip";
      } elsif (req.http.Accept-Encoding ~ "deflate") {
        set req.http.Accept-Encoding = "deflate";
      } else {
        remove req.http.Accept-Encoding;
      }
    }

    if (req.url ~ "\.(js|css|jpg|jpeg|png|gif|gz|tgz|bz2|tbz|mp3|ogg|swf)$") {
        return (lookup);
    }

    if (req.backend.healthy) {
        set req.grace = 5m;
    } else {
        set req.grace = 1h;
    }

    return (lookup);
}

sub vcl_fetch {

    if(req.request != "POST" && beresp.http.x-logged-in == "False") {
        unset beresp.http.Set-Cookie;
    }

    set beresp.grace = 1h;

    if (beresp.status == 503 || beresp.status == 502 || beresp.status == 501 || beresp.status == 500) {
      set beresp.grace = 60s;
      return (restart);
    }

    unset beresp.http.etag;

    if(beresp.http.Cache-Control == "no-cache" || beresp.http.Cache-Control == ""){
        set beresp.http.Cache-Control = "max-age=300, public, must-revalidate";
    }

    set beresp.ttl = 5m;

    return (deliver);
}
