ネットワークをデュアルチャンネルにしてからというもの快適そのもの。遅い回線を分けて分業体制にしたのがよかったのか、Wiiの更新もスムーズにいけるようになりました。Time Capsuleへのバックアップも以前に比べて早く終わってくれて助かります。
リンク速度270Mbit/秒というのも関係しているのかな。今のところ、この速度を出せるのはMacBook AirとMacBook Pro (Early 2008)だけらしいのでありがたいことです。
そこで、遅い回線と早い回線とでPingに違いがあるのかネットワークユーティリティを使って調べてみました。

誤差の範囲内だけどMacBookの方がなぜか速い…。
