It's widely mentioned that Redis is "Blazing Fast" and MongoDB is fast too. But, I'm having trouble finding actual numbers comparing the results of the two. Given similar configurations, features and operations (and maybe showing how the factor changes with different configurations and operations), etc, is Redis 10x faster? 2x faster? 5x faster?
I'm ONLY speaking of performance. I understand that MongoDB is a different tool and has a richer feature set. This is not the "Is MongoDB better than Redis" debate. I'm asking, by what margin does Redis outperform MongoDB?
At this point, even cheap benchmarks are better than no benchmarks.
