Detailed explanation of Hibernate Cache Technology and hibernate CacheReprinted with the source: http://www.cnblogs.com/xiaoming0601/p/5882980.html一: it does not mean the first-level cache of the computer's memory or CPU; cache is a strategy to reduce the frequency of application access to physical data sources and improve the running performance of applications.
As we all know, when the system reads the data, it is hundreds of times times faster to read from memory than from the hard disk. Therefore, most applications now use the cache (a storage area in memory) to maximize the operational efficiency of the system. MySQL database is no exception. Here, the author will combine their work experience, to discuss with you, MySQL Database Cache management skills: How to

It's easy to build complex and dynamic content using Drupal. But a little careless, you will pay the price for this easy. Complex database queries and costly calculations can lead to page performance problems when users view certain complex and dynamic pages. One solution is to turn on page caching in the DRUAPL background page. When the page cache is turned on, you can significantly reduce the number of database queries on some pages to improve page
The cache size is one of the important indicators of the CPU. Its structure and size have a great impact on the CPU speed. To put it simply, cache is used to store frequently-used or forthcoming data or commands. When these data or commands are needed, they are directly read from the cache, this is much faster than reading data from the memory or even the hard di
The cache is literally divided into two types: "slow" and "save ". The cache principle we mentioned in the previous section is actually a "Storage" word and how to access it. A general review is the hashcode corresponding to the key. The hashcode is used as the array subscript for access. Because of hash conflicts, the speed is not as high as O (1), but it is also very fast. Let's talk about the "slow" stra
