magento - magento で実行するニスの設定

Question

Magento を使用して EC サイトを作成しています。

私はnginx、php5-fpmを使用しています。

私は512MBのRAMと4CPUコアを持っています。

この仕様のワニスを使いたいです。サーバーが最小の遅延で最大のリクエストを処理できるようにするには、ワニス構成にどの値を設定すればよいか知りたいですか? ワニスの構成をいくつか試してみましたが、ワニスを使用しない場合よりも応答時間が長くなります。

これは私がいつも使っているセットアップです。Magento用のVarnishモジュールを搭載したPageCacheに由来します。私は実際にこれを設定することについて書きました

# This is a basic VCL configuration file for PageCache powered by Varnish for Magento module.

# default backend definition.  Set this to point to your content server.
backend default {
  .host = "127.0.0.1";
  .port = "8080";
}

# admin backend with longer timeout values. Set this to the same IP & port as your default server.
backend admin {
  .host = "127.0.0.1";
  .port = "8080";
  .first_byte_timeout = 18000s;
  .between_bytes_timeout = 18000s;
}


# add your Magento server IP to allow purges from the backend
acl purge {
  "localhost";
  "127.0.0.1";
}
