Specifying global EhCache capacity

问题 I am trying to migrate my project code from OSCache to EhCache. We have used OSCache not only as a second-level Hibernate cache provider but also to store other objects of a different nature. They all happily shared the same cache instance without any collisions due to non-overlapping cache keys. One big difference when moving towards EhCache is that each region has its different cache instance. This is potentially good as it can improve lookup speed as data of the different nature resides

Never used a cache like this before. The problem is that I want to load 500,000 + records out of a database and do some selecting/filtering wicked fast. I'm thinking about using a cache, and preliminarily found EHCache and OSCache , any opinions? They're both pretty solid projects. If you have pretty basic caching needs, either one of them will probably work as well as the other. You may also wish to consider doing the filtering in a database query if it's feasible. Often, using a tuned query that returns a smaller result set will give you better performance than loading 500,000 rows into

什么是性能 有人说性能就是访问速度快慢,这是最直观的说法,也是用户的真实体验。一个用户从输入网址到按下回车键,看到网页的快慢,这就是性能。对于我们来说,需要去挖掘这个过程,因为这决定我们怎么去做性能优化。 这中间发生了什么? 用户访问网站的整个流程:用户输入网站域名,通过DNS解析,找到目标服务器IP,请求数据经互联网达到目标服务器,目标服务器收到请求数据,进行处理(执行程序、访问数据库、文件服务器等)。处理完成,将响应数据又经互联网返回给用户浏览器,浏览器得到结果进行计算渲染显示给用户。 我们把整个过程,分为三段路径: 1、第一段在用户和浏览器端,主要负责发出用户请求,以及接受响应数据进行计算渲染显示给用户; 2、第二段在网络上,负责对请求数据、响应数据的传输; 3、第三段在网站服务器端,负责对请求数据进行处理(执行程序、访问数据库、文件等),并将结果返回; 第一路径 第一路径花费的时间包括输入域名发起请求的时间和浏览器收到响应后计算渲染的时间。 输入域名发起请求,实质过程是: 1、用户在浏览器输入要访问的网站域名; 2、本地DNS请求网站授权的DNS服务器对域名进行解析,并得到解析结果即IP地址(并将IP地址缓存起来)。 3、向目标IP地址发出请求。 从这个过程我们可以看到,优化的地方主要是减少DNS解析次数,而如果用户浏览器设置了缓存
