望解答！linux操作系统优化方法是啥

你好，linux操作系统优化方法
1、检查你的gcc版本：注意你的gcc版本必须在3.0以上。#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。◆i386(Intel)：CHOST=\\\\i386-pc-linux-gnu\\\\CFLAGS=\\\\-march=i386-O3-pipe-fomit-frame-pointer\\\\CXXFLAGS=\\\\-march=i386-O3-pipe-fomit-frame-pointer\\\\◆i486(Intel)：CHOST=\\\\i486-pc-linux-gnu\\\\CFLAGS=\\\\-march=i486-O3-pipe-fomit-frame-pointer\\\\CXXFLAGS=\\\\-march=i486-O3-pipe-fomit-frame-pointer\\\\◆Pentium1(Intel)CHOST=\\\\i586-pc-linux-gnu\\\\CFLAGS=\\\\-march=pentium-O3-pipe-fomit-frame-pointer\\\\CXXFLAGS=\\\\-march=pentium-O3-pipe-fomit-frame-pointer\\\\◆PentiumMMX(Intel)CHOST=\\\\i586-pc-linux-gnu\\\\CFLAGS=\\\\-march=pentium-mmx-O3-pipe-fomit-frame-pointer\\\\CXXFLAGS=\\\\-march=pentium-mmx-O3-pipe-fomit-frame-pointer\\\\◆PentiumPRO(Intel)CHOST=\\\\i686-pc-linux-gnu\\\\CFLAGS=\\\\-march=pentiumpro-O3-pipe-fomit-frame-pointer\\\\CXXFLAGS=\\\\-march=pentiumpro-O3-pipe-fomit-frame-pointer\\\\◆PentiumII(Intel)CHOST=\\\\i686-pc-linux-gnu\\\\CFLAGS=\\\\-march=pentium2-O3-pipe-fomit-frame-pointer\\\\CXXFLAGS=\\\\-march=pentium2-O3-pipe-fomit-frame-pointer\\\\◆Celeron(Mendocino),akaCeleron1(Intel)CHOST=\\\\i686-pc-linux-gnu\\\\CFLAGS=\\\\-march=pentium2-O3-pipe-fomit-frame-pointer\\\\CXXFLAGS=\\\\-march=pentium2-O3-pipe-fomit-frame-pointer\\\\◆PentiumIII(Intel)CHOST=\\\\i686-pc-linux-gnu\\\\CFLAGS=\\\\-march=pentium3-O3-pipe-fomit-frame-pointer\\\\CXXFLAGS=\\\\-march=pentium3-O3-pipe-fomit-frame-pointer\\\\◆Celeron(Coppermine)akaCeleron2(Intel)CHOST=\\\\i686-pc-linux-gnu\\\\CFLAGS=\\\\-march=pentium3-O3-pipe-fomit-frame-pointer\\\\CXXFLAGS=\\\\-march=pentium3-O3-pipe-fomit-frame-pointer\\\\◆Celeron(Willamette)(Intel)CHOST=\\\\i686-pc-linux-gnu\\\\CFLAGS=\\\\-march=pentium4-O3-pipe-fomit-frame-pointer\\\\CXXFLAGS=\\\\-march=pentium4-O3-pipe-fomit-frame-pointer\\\\◆Pentium4(Intel)CHOST=\\\\i686-pc-linux-gnu\\\\CFLAGS=\\\\-march=pentium4-O3-pipe-fomit-frame-pointer\\\\CXXFLAGS=\\\\-march=pentium4-O3-pipe-fomit-frame-pointer\\\\◆EdenC3/Ezra(Via)CHOST=\\\\i586-pc-linux-gnu\\\\CFLAGS=\\\\-march=i586-m3dnow-O3-pipe-fomit-frame-pointer\\\\CXXFLAGS=\\\\-march=i586-m3dnow-O3-pipe-fomit-frame-pointer\\\\◆K6(AMD)CHOST=\\\\i586-pc-linux-gnu\\\\CFLAGS=\\\\-march=k6-O3-pipe-fomit-frame-pointer\\\\CXXFLAGS=\\\\-march=k6-O3-pipe-fomit-frame-pointer\\\\◆K6-2(AMD)CHOST=\\\\i586-pc-linux-gnu\\\\CFLAGS=\\\\-march=k6-2-O3-pipe-fomit-frame-pointer\\\\CXXFLAGS=\\\\-march=k6-2-O3-pipe-fomit-frame-pointer\\\\◆K6-3(AMD)CHOST=\\\\i586-pc-linux-gnu\\\\CFLAGS=\\\\-march=k6-3-O3-pipe-fomit-frame-pointer\\\\CXXFLAGS=\\\\-march=k6-3-O3-pipe-fomit-frame-pointer\\\\◆Athlon(AMD)CHOST=\\\\i686-pc-linux-gnu\\\\CFLAGS=\\\\-march=athlon-O3-pipe-fomit-frame-pointer\\\\CXXFLAGS=\\\\-march=athlon-O3-pipe-fomit-frame-pointer\\\\◆Athlon-tbird,akaK7(AMD)CHOST=\\\\i686-pc-linux-gnu\\\\CFLAGS=\\\\-march=athlon-tbird-O3-pipe-fomit-frame-pointer\\\\CXXFLAGS=\\\\-march=athlon-tbird-O3-pipe-fomit-frame-pointer\\\\◆Athlon-tbirdXP(AMD)CHOST=\\\\i686-pc-linux-gnu\\\\CFLAGS=\\\\-march=athlon-xp-O3-pipe-fomit-frame-pointer\\\\CXXFLAGS=\\\\-march=athlon-xp-O3-pipe-fomit-frame-pointer\\\\◆Athlon4(AMD)CHOST=\\\\i686-pc-linux-gnu\\\\CFLAGS=\\\\-march=athlon-4-O3-pipe-fomit-frame-pointer\\\\CXXFLAGS=\\\\-march=athlon-4-O3-pipe-fomit-frame-pointer\\\\◆AthlonXP(AMD)CHOST=\\\\i686-pc-linux-gnu\\\\CFLAGS=\\\\-march=athlon-xp-O3-pipe-fomit-frame-pointer\\\\CXXFLAGS=\\\\-march=athlon-xp-O3-pipe-fomit-frame-pointer\\\\◆AthlonMP(AMD)CHOST=\\\\i686-pc-linux-gnu\\\\CFLAGS=\\\\-march=athlon-mp-O3-pipe-fomit-frame-pointer\\\\CXXFLAGS=\\\\-march=athlon-mp-O3-pipe-fomit-frame-pointer\\\\◆603(PowerPC)CHOST=\\\\powerpc-unknown-linux-gnu\\\\CFLAGS=\\\\-O3-pipe-fsigned-char\\\\CXXFLAGS=\\\\-O3-pipe-fsigned-char\\\\◆603e(PowerPC)CHOST=\\\\powerpc-unknown-linux-gnu\\\\CFLAGS=\\\\-O3-pipe-fsigned-char\\\\CXXFLAGS=\\\\-O3-pipe-fsigned-char\\\\◆604(PowerPC)CHOST=\\\\powerpc-unknown-linux-gnu\\\\CFLAGS=\\\\-O3-pipe-fsigned-char\\\\CXXFLAGS=\\\\-O3-pipe-fsigned-char\\\\◆604e(PowerPC)CHOST=\\\\powerpc-unknown-linux-gnu\\\\CFLAGS=\\\\-O3-pipe-fsigned-char\\\\CXXFLAGS=\\\\-O3-pipe-fsigned-char\\\\◆750akaasG3(PowerPC)CHOST=\\\\powerpc-unknown-linux-gnu\\\\CFLAGS=\\\\-mcpu=750-O3-pipe-fsigned-char-mpowerpc-gfxopt\\\\CXXFLAGS=\\\\-mcpu=750-O3-pipe-fsigned-char-mpowerpc-gfxopt\\\\◆7400,akaG4(PowerPC)CHOST=\\\\powerpc-unknown-linux-gnu\\\\CFLAGS=\\\\-mcpu=7400-O2-pipe-fsigned-char-maltivec-mabi=altivec-mpowerpc-gfxopt\\\\CXXFLAGS=\\\\-mcpu=7400-O2-pipe-fsigned-char-maltivec-mabi=altivec-mpowerpc-gfxopt\\\\-fsigned-char-maltivec-mabi=altivec-mpowerpc-gfxopt\\\\◆7450,akaG4secondgeneration(PowerPC)CHOST=\\\\powerpc-unknown-linux-gnu\\\\CFLAGS=\\\\-mcpu=7450-O2-pipe-fsigned-char-maltivec-mabi=altivec-mpowerpc-gfxopt\\\\CXXFLAGS=\\\\-mcpu=7450-O2-pipe-fsigned-char-maltivec-mabi=altivec-mpowerpc-gfxopt\\\\◆PowerPC(Ifyoudon\\\\tknowwhichone)CHOST=\\\\powerpc-unknown-linux-gnu\\\\CFLAGS=\\\\-O3-pipe-fsigned-char-mpowerpc-gfxopt\\\\CXXFLAGS=\\\\-O3-pipe-fsigned-char-mpowerpc-gfxopt\\\\◆SparcCHOST=\\\\sparc-unknown-linux-gnu\\\\CFLAGS=\\\\-O3-pipe-fomit-frame-point
