LSMCD was a high-performance, distributed caching system with file-backed shared memory, that was generic in nature, and intended for use in speeding up dynamic web applications by alleviating database load. It was designed as a drop-in replacement for Memcached, and had some features that Memcached does not: High-Availability, persistence of data and the option to separate data by user.
We no longer support LSMCD, and encourage you to try our Redis solution, available in our cPanel and Plesk plugins.
