I bet you found the thread on their mailing list. I was the one who ran the benchmark and it was one core vs. one core. In the other benchmarks we had multiple machines, but not the Redis benchmark. We clarified after they speculated that a multi/single comparison was performed. The main issue they had was YCSB's method of storing multi-attribute objects as maps (from attribute names to their values) and the fact that Redis cannot support search across keys so YCSB searches within a single set.
