INNODBibdata 有30G2. 有近2万张表表的字段比较少(基本上10几个字段最多有40个字段)3. 大部分表的记录数不超过3万条只有个别表的记录有百万条的数量级。【数据库使用情况】1. 连接只有几十个其中有几个连接是后台守护程序在用查询和写入的频率很高(类似实时系统)。【问题描述】1. 在MYSQL控制台下面不管是什么操作(查询/更新)都非常慢(一张1万条记录的用户表查记录数都要几秒~几十秒)。而此种情况下mysqld占用约500M内存CPU基本上都是2%(好像不工作)。重启MYSQL后稍微好一点但不一会又开始很慢。对比最奇怪的是之前的速度比较正常mysqld 占用约500M内存CPU占用50%MYSQL查询速度比较OK(都是0.0X秒)。我是MYSQL菜鸟请大虾指教是什么原因附MYSQL配置# MySQL Server Instance Configuration File# ----------------------------------# Generated by the MySQL Server Instance Configuration Wizard### Installation Instructions# ----------------------------------## On Linux you can copy this file to /etc/my.cnf to set global options,# mysql-data-dir/my.cnf to set server-specific options# (localstatedir for this installation) or to# ~/.my.cnf to set user-specific options.## On Windows you should keep this file in the installation directory# of your server (e.g. C:\Program Files\MySQL\MySQL Server X.Y).
