7.3. Carrying Out Performance Benchmarking¶
When testing the performance of a Virtuozzo Storage cluster and comparing it with non-Virtuozzo Storage 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 Virtuozzo Storage cluster using the FUSE interface provides a convenient view into the cluster but is not optimal for performance. Therefore, do benchmarks from inside containers and virtual machines.
Keep in mind that the data replication factor affects the cluster performance: clusters with two replicas are slightly faster than those with three replicas.
