How fast? It depends on a lot of things - which commands you are using, the type of data, and so on. But Redis' performance tends to be measured in tens of thousands, or hundreds of thousands of operations **per second**. You can run `redis-benchmark` (which is in the same folder as the `redis-server` and `redis-cli`) to test it out yourself.
-I once changed code which used a traditional model to using Redis. A load test I wrote took over 5 minutes to finish using the relational model. It took about 150ms to complete in Redis. You won't always get that sort of massive gain, but it hopefully gives you an idea of what we are talking about

It's important to understand this aspect of Redis because it impacts how you interact with it. Developers with an SQL background often work at minimizing the number of round trips they make to the database. That's good advice for any system, including Redis. However, given that we are dealing with simpler data structures, we'll sometimes need to hit the Redis server multiple times to achieve our goal. Such data access patterns can feel unnatural at first, but in reality it tends to be an insignificant cost compared to the raw performance we gain.
