    • 问题原因：

      4. 改阻塞方式为非阻塞方式来处理请求。

      6. 修改容器配置，增加线程池大小以及等待队列长度。

  •  The connection is made, the request for the page is sent, and the connection is dropped.  This makes getting the number of people currently "on" a site rather difficult.  You don''t have a connection to everyone so you can''t simply count them.  You also have no way of telling if they''re going to come back and request another page or not until they do or until you decide you''ve waited long enough that they aren''t going to!
  • if a visitor''s browser doesn''t support them or has them turned off, each request is looked upon as a new session and can cause problems for a site which uses a lot of Session objects or does a lot of processing in Session_OnStart.

网站运维之道 之容量规划 - DBA notes

  • 基本上都会采用 RRDtool （http://oss.oetiker.ch/rrdtool/）来做。 RRDtool 也已经是业界的事实上的标准，但毕竟 RRDtool 只能算是一套引擎。而规模化的数据管理工作则需要求助其它工具，则不能不提 Cacti （http://www.cacti.net/）这是现在相当通用的做法。
