Ideally benchmarks should only substitute for real applications if the application is unavailable, or too difficult or costly to port to a specific processor or computer system. If performance is critical, the only benchmark that matters is the target environment's application suite.

Features of benchmarking software may include recording/[[data export|exporting]] the course of performance to a [[spreadsheeet]] file, visualization such as drawing [[line graph]]s or [[color-coded]] tiles, and pausing the process to be able to resume without having to start over. Software can have additional features specific to its purpose, for example, disk benchmarking software may be able to optionally start measuring the disk speed within a specified range of the disk rather than the full disk, measure [[random access]] reading speed and [[latency (engineering)|latency]], have a "quick scan" feature which measures the speed through samples of specified intervals and sizes, and allow specifying a [[Block (data storage)|data block]] size, meaning the number of requested bytes per read request.<ref>Software: HDDScan, GNOME Disks</ref>
