Carrying Out Performance Benchmarking

When testing the performance of a Parallels Cloud Storage cluster and comparing it with non-Parallels Cloud 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 Parallels Cloud 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.
