Dbench

Dbench is a benchmark designed by the Samba project as a free alternative to netbench, but dbench contains only file-system calls for testing the disk performance.

To run this test with the Phoronix Test Suite, the basic command is: phoronix-test-suite benchmark dbench.

OpenBenchmarking.org metrics for this test profile configuration based on 4,932 public results since 6 December 2010 with the latest data as of 16 October 2021.

Below is an overview of the generalized performance for components where there is sufficient statistically significant data based upon user-uploaded results. It is important to keep in mind particularly in the Linux/open-source space there can be vastly different OS configurations, with this overview intended to offer just general guidance as to the performance expectations.
