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)
