http://redis.io/topics/latency http://redis.io/topics/latency : Redis is mostly single threaded since actually from Redis 2.4 we use threads in Redis in order to perform some slow I/O operations in the background, mainly related to disk I/O Could this affect the benchmarks then? I don't know if it does, but if the benchmark is also writing to disk, wouldn't a dual core machine perform better?
