Scaling Memcached: 500,000+ Operations/Second with a Single-Socket UltraSPARC T2

A software-based distributed caching system such as memcached is an important piece of today's largest Internet sites that support millions of concurrent users and deliver user-friendly response times. The distributed nature of memcached design transforms 1000s of servers into one large caching pool with gigabytes of memory per node. This blog entry explores single-instance memcached scalability for a few usage patterns.

Table below shows out-of-the-box (no custom OS rewrites or networking tuning required) performance with 10G networking hardware and one single-socket UltraSPARC T2-based server with 8 cores and 8 threads per core (64 threads on a chip)...

Object Size / Ops/Sec / Bandwidth
100 bytes / 530,000 / 1.2 Gb/s
2048 bytes / 370,000 / 6.9 Gb/s
4096 bytes / 255,000 / 9.2 Gb/s
