You should now have extensive knowledge on how to tune a Ceph cluster to maximize performance and achieve lower latency. Through the use of benchmarks, you should now be able to perform before and after tests to confirm whether your tunings have had the desired effect. It is worth reviewing the official Ceph documentation to get a better understanding of some of the other configuration options that may be beneficial to your cluster.

You have also learned about some of the key factors that effect Ceph performance and how to tune them, such as CPU clock speed and sleep states. Ensuring that the infrastructure your Ceph cluster is running on is running at peak performance will ensure that Ceph can perform at its very best.

In the next chapter we will discuss tiering and how it can be used to increase performance by combining different disk technologies together.
