http://www.kitcc.org/~bugyo/b-log/?p=272 気が付いたら自宅LAN内のNICがすべてギガビット対応だったのでギガビットスイッチ(CG-SW05GTPLXB)を3144円で購入。
わりと安かった。

ジャンボフレーム対応なのでMTUを9000に設定。
FreeBSDでは

ifconfig vge0 mtu 9000

Widowsではデバイスマネージャーから”ネットワーク”カテゴリにあるNICのプロパティを開いて詳細設定で設定できる。

FTPのスループットを測ってみた。
使用したNICはGbE-PCI2(ホスト1)、nForce4(ホスト2)、Intel PRO/1000 MT Mobile Connection(ホスト3)。
ホスト1がサーバ機でFTPサーバ。
1GBのファイルをGETしたときの時間を計測。
ちなみにファイルは

dd if=/dev/random of=dummy.tmp bs=1024 count=1048576

で作成した。
ケーブル長は2mくらい。

結果：

ホスト スループット
ホスト1→ホスト2 30.97MB/s
ホスト1→ホスト3 34.67MB/s

 

ホスト3(Intel製NIC)の方が12%程度速い。
別々のケーブルで計測したのでまだ分からないけど、チップの差なんだろうか。

※ディスク速度がボトルネックだった→GbEの速度
