If you've read anything about scaling large websites, you've probably heard about memcached. memcached is a high-performance, distributed memory object caching system. Here at Facebook, we're likely the world's largest user of memcached. We use memcached to alleviate database load. memcached is already fast, but we need it to be faster and more efficient than most installations. We use more than 800 servers supplying over 28 terabytes of memory to our users. Over the past year as Facebook's popularity has skyrocketed, we've run into a number of scaling issues. This ever increasing demand has required us to make modifications to both our operating system and memcached to achieve the performance that provides the best possible experience for our users.
