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

Understanding about Cache Usage and understanding about Cache Usage First of all, the advantage of caching is that the cache stores data in the memory and extracts the data from the memory when needed (compared with the data obtained from the hard disk, the cache speed is much faster) prompt speed

I. OverviewThe idea of caching can be applied at all levels of software layering. It is an internal mechanism that is not perceptible to the outside world.The database itself is cached, and persistent layers can be cached. (e.g. hibernate, 1-and 2-level caches)The business layer can also have a cache (but in general, this is a process domain and will not be cached).The presentation layer/Data Service layer (the presentation layer of the traditional we

1. Why Use CachingHibernate uses caching to reduce the number of accesses to the database, which improves hibernate execution efficiency. There are two types of caches in Hibernate: first-level cache and level two cache.2. First level cacheHibenate cache, also known as the session cache, when invoking the session's Sav

Preface As the name suggests, the File Cache to memory cache is to convert the data stored in the file to the memory, so that disk operations can be converted to memory operations, which can greatly improve the data access speed, and distributed deployment of cache data. For more information about file caching and memory caching, see glossary. PrincipleThe prin

The role of Refresh_pattern:Used to determine how long a page stays in the cache after it enters the cache. Refresh_pattern only works on a page where the backend does not have a expires expiration, such as a forum page, and does not work on pages similar to Apache Mod_expires. Grammar:Refresh_pattern [-i] regexp min percent max [options] Several concepts:Resource age = Time the object entered the

What's the difference between Page cache and buffer cache? Most of the time we do not know the system in the IO operation is to walk the page cache or buffer cache? In fact, the buffer cache and page cache are two simpler concepts

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

ASP. NET 2.0 retains all the caching functions of ASP. NET 1.1. It also adds new functions and enhances existing functions. The new features include cache configuration files, custom cache dependencies, SQL cache dependencies, and creating dynamic content on the cache page (with ca
