Memcached is a distributed memory object cache system developed by danga.com (technical team operating livejournal) to reduce database load and improve performance in dynamic systems. The number of dynamic page views per second on the LJ is several thousand, and the number of users is 7 million. Memcached greatly reduces the database load and makes it easier to allocate resources for faster access. I believ

Memcached:• Location: it is placed on the server side and communicated through Socket. • Data: Key-Value Pair Storage • Memory processing algorithms: • In essence, it is a large hash table. The key cannot exceed 255 characters. • Memory Model: Memcache pre-partitions disposable memory space (Slab). Each partition is further divided into multiple chunks with a size of 1 MB, but in the same partition: the block length (bytes) is fixed. • Insert data: F

Memcached is the Holy one?In data-driven web development, it is often repeated to remove the same data from the database, which greatly increases the database load. Caching is a good way to solve this problem. But httpruntime.cache in ASP. Although it can be implemented to cache the page locally, but still not flexible, at this time memcached may be what you want.Memcached is a high-performance distributed
