“In a release focused on improving thread scalability and
performance, the developers of Memcached, the distributed memory
object caching system, say that version 1.4.10 can now “feed data
back faster than any network card can support”.The performance enhancements saw developers report batched
multiple key fetches per second rising from 1.6 million keys/second
to “around 3.7 million keys/sec” on a quad core system with between
3 and 6 worker threads; more than six worker threads reduced speed,
while a system with more cores was able to reach six million
keys/second.
