测试命令:
mysqlslap -uroot -pzhanglin --concurrency=1000 --iterations=10 --auto-generate-sql --auto-generate-sql-load-type=mixed --auto-generate-sql-add-autoincrement --engine=myisam --number-of-queries=10 --debug-info
  #备注本次测试以1000个并发线程、测试10次,自动生成SQL测试脚本、读、写、更新混合测试、自增长字段、测试引擎为myisam、共运行10次查询,输出cpu资源信息
 
mysqlslap --concurrency=10,200,1000 --iterations=20 --number-int-cols=8 --number-char-cols=30 --auto-generate-sql --auto-generate-sql-add-autoincrement --auto-generate-sql-load-type=read --engine=myisam,innodb --number-of-queries=5000 --verbose --socket=/tmp/mysql/mysql.sock -uroot -pzhanglin
   #系统脚本测试,增加int型 8列char 型30列,测试2种引擎myisam,innodb读的性能,分别用10,200,1000个客户端对服务器进行测试总共5000个查询语句 执行20次查询
