Memcached is a popular key-value caching service used by web service delivery companies to reduce the latency of serving data to consumers and reduce load on back-end database servers. It has a scale out architecture that easily supports increasing throughput by simply adding more memcached servers, but at the individual server level scaling up to higher core counts is less rewarding. In this talk we introduce optimizations that break through such scalability barriers and allow all cores in a server to be used effectively. We explain new algorithms implemented to achieve an almost 6x increase in throughput while maintaining a 1ms average latency SLA by utilizing concurrent data structures, a new cache replacement policy and network optimizations.
