こんな結果になりました。ベンチマークの結果だけからみるとDiskのI/Oはかなり高いです。比較としてLinodeを出してますが、AWSと比較してもかなり差のある内容になってます。 ただ、惜しむらくはCPUとメモリのバランスが悪く、コア数が1個からスタートとなってる関係でおなじさくらのサービスのVPSとのスコア差があまりないことです。比較対象としてさくらのVPSの1GプランでのUbuntu10.04.03で取ったUnixBenchを以下に掲げます。コア単体で見ると差があるのですが、さくらのVPSの1Gプランではコア数が2個あるので、あまり差がなくなっているという実例です。

ちなみにこのさくらのVPSの1GプランではDiskが2つに別れて提供されているため、LVMで1つにまとめているので、LVMを使わない設定でインストールするとまた数字が変わるかもしれません
