Performance tuning and benchmarking make your Ceph cluster production class. You should always fine-tune your Ceph cluster before moving it to production usage from preproduction, development, or testing. Performance tuning is a vast subject, and there is always a scope of tuning in every environment. You should use performance tools to meter the performance of your Ceph cluster, and based on the results, you can take necessary actions.

In this chapter, have reviewed most of the tuning parameters for your cluster. You have learned advanced topics such as performance tuning from hardware as well as software perspectives. This chapter also included a detailed explanation on Ceph erasure coding and cache-tiering features, followed by the Ceph inbuilt benchmarking tool, RADOS bench.
