稀饭的国度

关键字: mysql compile
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)
