netperfを使った測定

netperf Server側:
OS: Debian etch Testing / Linux 2.6.16-2-686
CPU: PentiumIII 933MHz x 2
Memory: 1GB

netperf Client側:
OS: Debian etch Testing / Linux 2.6.16-2-686
CPU: PnetiumIII 900MHz x 4 on VMWare server
Memory: 256MB

まずは実ネットワークの測定結果

105472           10.00         865             45.32

結果

    実ネットワーク　P2P@i
TCP    51.7Mbps   30.0Mbps
UDP   383.4Mbps   45.8Mbps

VM使ってこれだけでれば，動画ぐらいはストリーム出来そうだな．
