VMmark is a freeware virtual machine benchmark software suite from VMware, Inc.
The suite measures the performance of virtualized servers while running under load on a set of physical hardware.
The VMmark software collects performance statistics that are relevant to each type of application, such as commits per second for database servers, or page accesses per second for web servers.
When evaluating a system's performance, the VMmark software first calculates a score for each tile, culled from the performance statistics produced by each VM, and aggregates the per-tile scores into a final number.
