实用技巧：Linux操作系统优化方法介绍

经验谈：如何使你的系统达到最优化？ 1、检查你的gcc版本： #gcc--version 2、获取你的cpu的型号： cat/proc/cpuinfo 3、在/etc/下建立make.conf文件，并根据cpu的型号写入不同内容。注意你的gcc版本必须在3.0以上。 i386(Intel)： CHOST=\"i386-pc-linux-gnu\"

好了，这样做后你编译出的程序运行效率将比以前高很多！只要你有时间，你可以把你的系统如redhatlinux9.0的源代码（后缀.src.rpm）全部重新编译一次，你会发现你的RedhatLinux系统将比原来快一大截！ （责任编辑：凌云通）
