What is LiteSpeed Memcached?
LiteSpeed Memcached (LSMCD) is a high-performance, distributed caching system with file-backed shared memory. It is an upgraded version of Memcached with outstanding advantages such as: high availability, durability and individuality.
- High availability means that if one or more of your servers goes down, you can still access and update your data as if the servers were up and running.
- Data persistence means that anything you put into the LSMCD stays in the LSMCD unless you notify that they have changed.
- Distinctiveness means that each user has their own data in the repository. By isolating each user’s data, you can improve data security and potentially charge users for access to the data.
To put it simply, LSMCD will help you cache queries to the website’s database. The combination of LSMCD, LSCache and OpCode Cache will give your website a perfect performance when it comes to both fast loading speed and good load capacity.
