| This test measure system wide performance by running the following tests: |
| - Dhrystone - focuses on string handling. |
| - Whetstone - measure floating point operations. |
| - Execl Throughput - measure the number of execl calls per second. |
| - File Copy |
| - Pipe throughput |
| - Pipe-based context switching |
| - Process creation - number of times a process can fork and reap |
| - Shell Scripts - number of times a process can start and reap a script |
| - System Call Overhead - estimates the cost of entering and leaving the |
| kernel. |
