Maximizing Storage Cluster
Performance
This chapter describes recommendations for maximizing the performance of your storage cluster.
Note: Also consider updating hardware nodes in the cluster.
6.1 Carrying Out Performance Benchmarking
When testing the performance of a storage cluster and comparing it with third-party setups:
• Compare configurations with similar redundancy levels. For example, it is incorrect to compare the
performance of a cluster with two or three replicas per data chunk with a standalone server that does
not use any data redundancy, like RAID 1, 10, or 5.
• Take into account the usage of file system interfaces. Keep in mind that mounting a storage cluster
using the FUSE interface provides a convenient view into the cluster but is not optimal for performance.
Therefore, do benchmarks from inside virtual machines and containers.
• Keep in mind that the data replication factor affects the storage cluster performance: clusters with two
replicas are slightly faster than those with three replicas.
