推荐答案

在每个基于站点或基于Web的应用程序中，有些数据不会经常更改，因此非常需要很多最终用户经常这样做.示例包括商品类别列表，电子商店的产品类别和产品项目，国家和州列表等等.提高站点性能的最常见解决方案是为该类型的数据实现缓存系统，以便一旦从数据存储中检索到数据，该数据将在内存中保留一定的时间间隔，并随后请求相同的数据将从内存缓存中检索它，从而避免往返数据库服务器并运行另一个查询.这将节省处理时间和网络流量，从而为用户提供更快的输出

在ASP.NET中进行缓存 [

In every site- or web-based application, there is some data that doesn’t change very often, which is requested very frequently by a lot of end users. Examples are a list of article categories, an e-store''s product categories and product items, a list of countries and states, and so on. The most common solution to increase the performance of your site is to implement a caching system for that type of data, so that once the data is retrieved from the data store, it will be kept in memory for some interval, and subsequent requests for the same data will retrieve it from the memory cache, avoiding a round trip to the database server and running another query. This will save processing time and network traffic and, thus, produce faster output to the user
