Because Redis is in part I/O bound, this is why Redis 2.0, and even more Redis 2.2 (currently git master) are using the spare CPU in order to use less memory, with specially encoding for small lists, sets, hashes. Btw 25% the speed means a lot slower :) My guess was that the difference for small keys that the redis-benchmark is stressing would be smaller. I think that with big lists or using the SORT command the difference will be bigger. Cheers, Salvatore
