TPS - Transactions Per Second（每秒傳輸的事物處理個數），即伺服器每秒處理的事務數，如果是InnoDB會顯示，沒有InnoDB就不會顯示。
TPS = (COM_COMMIT + COM_ROLLBACK)/UPTIME

use information_schema;
select VARIABLE_VALUE into @num_com from GLOBAL_STATUS where VARIABLE_NAME ='COM_COMMIT';
select VARIABLE_VALUE into @num_roll from GLOBAL_STATUS where VARIABLE_NAME ='COM_ROLLBACK';
select VARIABLE_VALUE into @uptime from GLOBAL_STATUS where VARIABLE_NAME ='UPTIME';
select (@num_com+@num_roll)/@uptime;

QPS - Queries Per Second（每秒查詢處理量）MyISAM 引擎
QUESTIONS/UPTIME

use information_schema;
select VARIABLE_VALUE into @num_queries from GLOBAL_STATUS where VARIABLE_NAME ='QUESTIONS';
select VARIABLE_VALUE into @uptime from GLOBAL_STATUS where VARIABLE_NAME ='UPTIME';
select @num_queries/@uptime;
