IE9 Beta

2010-09-20 · IT

Internet Explorer 9 (IE9) のベータ版をインストールしてみた。

**＜従来の環境＞
**　IE8 + Sleipnir 2.94 (Windows Vista SP2)　→　描写速度の測定結果 5898.6ms

　IE8 + Sleipnir 2.94 (Windows XP SP3)　→　描写速度の測定結果 8728.0ms

**＜IE9インストール後＞
**　IE9 Beta (Windows Vista SP2)　→　描写速度の測定結果 532.4ms

はえーよ！描写のにかかる時間が、当社比91%カット！
ホームページ見る時に、「ページ開くのがなんか遅い！」って思ってる人は、

　・自分が利用している回線速度
　・相手側サーバーの回線速度
　・自分のPCのハードウェア（CPUやメモリーなど）

以外に、ブラウザのエンジンを疑った方がいいのかもしれない。。
うちの環境では、IE8がボトルネックになってた。
というか、Chrome (Google) や Safari (Apple) に比べて、IE8がいかにダメか再確認。

**【IE9 の基本スペック】
**対応OS： Windows 7 / Vista
新機能：　HTML5、CSS3 に対応。新JavaScriptエンジン「Chakra」搭載。キャッシュ性能向上。
　　　　　　レンダリングにGPUハードウェアアクセラレーションを利用。

※なお、今回の動作速度の評価に使用したSunspiderは、
JavaScriptの使用（画面描画、暗号化、テキスト操作など）を測定するもので、
アプリケーション自体の実行速度を測定するものではない。

・・・ちなみに今回、そもそもIE9ベータ版をインストールするに至った動機は、
Awesome Drop という Andorid のアプリをインストールする際に、
HTML5対応のブラウザでないと動作しないから、IE9が必要だったから。
ベータが取れて、正式リリースされる日を待ってます。
