Apacheでmod_deflateを試してみる
VirtualBoxにCentOSをとりあえずインストール
の続き
Apacheでmod_deflateを試してみる。
Apacheのインストールと起動
まずは、Apacheをインストールして起動する。
$ sudo yum -y install httpd $ sudo service httpd start
http://サーバーのアドレス/
にアクセスして、デフォルトのページを表示する。
レスポンスヘッダーを見てみると、下記のようになっている。
ドキュメントのサイズは5KBほど。
Mac側からabコマンドで負荷をかけてみる。
mac$ ab -c 100 -n 10000 http://サーバーのアドレス/

mod_deflateの設定
mod_deflateを設定する。
httpd.confに下記を追加して、Apacheを再起動する。
$ sudo vi /etc/httpd/conf/httpd.conf ↓追加 <IfModule mod_deflate.c> SetOutputFilter DEFLATE AddOutputFilterByType DEFLATE text/html </IfModule>
$ sudo service http restart
http://サーバーのアドレス/
にアクセスして、レスポンスヘッダーを見てみると、下記のようになる。
ドキュメントのサイズは2KBほどになった。
Mac側からabコマンドで負荷をかけてみる。
（mod_deflateを有効にするには「-H 'Accept-Encoding: gzip,deflate'」を付ける必要あり）
mac$ ab -c 100 -n 10000 -H 'Accept-Encoding: gzip,deflate' http://サーバーのアドレス/

100KBのHTMLの場合
100KBのHTMLだとどうなるか試してみる。
まず、100KBのHTMLを生成する。
$ sudo yum -y install php $ sudo chown ユーザー名:ユーザー名 /var/www/html $ cd /var/www/html $ php -r '$s=range("a","z"); for($i=0;$i<102400;$i++) echo $s[array_rand($s)];' > 100kb.html
mod_deflateを設定していない場合とした場合でどれくらいかかるか測ってみる。
