1. -static 13%
--with-client-ldflags=-all-static
--with-mysqld-ldflags=-all-static
静态链接提高13%性能

2. -pgcc 1%
CFLAGS="-O3 -mpentiumpro -mstack-align-double" CXX=gcc \
CXXFLAGS="-O3 -mpentiumpro -mstack-align-double \
-felide-constructors -fno-exceptions -fno-rtti"
如果是Inter处理器，使用pgcc提高1%性能

3. Unix Socket 7.5%
--with-unix-socket-path=/usr/local/mysql/tmp/mysql.sock
使用unix套接字链接提高7.5%性能，所以在windows下mysql性能肯定不如unix下面

4. --enable-assembler
允许使用汇编模式(优化性能)

下面是总体的编译文件

编译代码
CFLAGS="-O3 -mpentiumpro -mstack-align-double" CXX=gcc \
CXXFLAGS="-O3 -mpentiumpro -mstack-align-double \
-felide-constructors -fno-exceptions -fno-rtti"

./configure --prefix=/usr/local/mysql5 \
