先週、ボーナスの使い道第一弾で新しいPCを買っちゃいました。
じゃじゃじゃじゃーん！
……ええ。Raspberry Piです。
もちろんPhotoshopなんか動きません。というか遅い！
とりあえず、１台目のRaspberry Piはそこらのサーバでは手に負えないような大容量のファイルやりとりに使う予定です。FTPサーバとしてはそこそこ動いてくれるらしいんで。
なので、一応同人向けサーバです（キリッ
盛大に遅いので、ベンチマーク取ってみました。
比較対象：自分のメインマシン(AMD Phenom II X6 1065T = 2.9GHz * 6コア)VirtualBox上のUbuntu 12.04 64bit環境
まずは、VirtualBox @ Phenom II X6 1065Tの環境。

Raspberry Pi, やっぱり遅いですよね（苦笑
