Executive Summary

Operators of dynamic, high-growth web sites are making extensive use of the open-source distributed cache system Memcached, in order to economically scale their web sites. By storing data in DRAM instead of in a database, response time improvements of 100x or more are typical.

But as these companies deploy ever-larger amounts of memory for use by Memcached, the memory efficiency shortcomings of Memcached become a concern.

This white paper will explain how standard Memcached manages and allocates memory, and compare it with memory management in Gear6 Web Cache, an enhanced distribution of Memcached that employs advanced technology to use memory much more efficiently.
