Memcached

Memcached is used as a web cache server.

Memcached is a free, open-source, high-performance distributed memory object caching system. It is an in-memory key-value storage system for small chunks of arbitrary data (strings or objects) from results of database queries, API calls, or page rendering. Memcached is used to cache database query results to reduce the number of database access times, which speeds up dynamic web applications and improves scalability.

Memcached can be deployed on a Kunpeng physical server or a VM hosted on a Kunpeng server. The multi-core Kunpeng processors and multi-channel memory further improve the Memcached performance.

Memcached is stored in the memory and has almost no drive I/O access. Therefore, the memory access capability has a great impact on the performance. The Kunpeng processors support 8-channel DDR4 access to deliver high performance. When large VMs and physical machines are used, the multi-core features of Kunpeng processors can greatly improve the Memcached performance.
