Redis is known as one of the fastest databases out there. But what if some of the limitations were removed, how fast could a stand-alone instance become? We often hear that Redis will likely become network bound or memory bound before it is CPU bound on performance limitations. Depending on your setup it could be any of these.

In this article we are going to discuss how we made a module that nearly doubles Redis performance!
