ここでは、UNIX BENCHを実行してみます。
■UNIX BENCHダウンロード先
http://www.hermit.org/Linux/Benchmarking/
（１）UNIX BENCH実行に必要なパッケージをインストールする。
[root@example ~]# yum -y install libX11-devel freeglut-devel# Xのベンチをしない場合は、上記パッケージをインストールしなくても大丈夫です。その場合は、Makefileの「GRAPHIC_TESTS = defined」をコメントアウトしてください。
（２）UNIX BENCH実行に必要なPerlモジュールをインストールする。
[root@example ~]# cpan -i Time::HiRes
（３）UNIX BENCHをダウンロードする。
[root@example ~]# wget http://www.hermit.org/Linux/Benchmarking/unixbench-5.1.2.tar.gz
（４）ダウンロードしたUNIX BENCHを解凍する。
[root@example ~]# tar zvxf unixbench-5.1.2.tar.gz
（５）UNIX BENCHの実行をする。
[root@example ~]# cd unixbench-5.1.2 [root@example unixbench-5.1.2]# make [root@example unixbench-5.1.2]# ./Run
・実行結果例
