MySQL监控MySQL服务器硬件和OS(操作系统)调优:1、有足够的物理内存,能将整个InnoDB文件加载到内存里 —— 如果访问的文件在内存里,而不是在磁盘上,InnoDB会快很多。2、全力避免 Swap 操作 — 交换(swapping)是从磁盘读取数据,所以会很慢。3、使用电池供电的RAM(...

有n个城市,m条路,从1走到n的道路的最大承载量,最大承载量就是走过的路的承载量的最小值。呵呵呵~~~再次举个栗子:假设n=3,m=3,连接1与2的城市的路的承载量为3,连接1与3的承载量是4,连接2与3的承载量是5,那么从1到3有2种走法:(1)1-2-3,承载量依次是3,5,那么最大承载量就是5;(2)1-3,承载量是4,最大承载量也是4,所以答案是4。...
