How much faster is Redis than mongoDB?

Question

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 simila

Answer 1

I think that the 2-3X on the shown benchmark are misleading, since if you it also depends on the hardware you run it on - from my experience, the 'stronger' the machine is, the bigger the gap (in favor of Redis) will be, probably by the fact that the benchmark hits the memory bounds limit pretty fast.

As for the memory capacity - this is partially true, since there are also ways to go around that, there are (commercial) products that writes back Redis data to disk, and also cluster (multi-sharded) solutions that overcome the memory-size limitation.
