The following results were acquired using the Linux port of release 2 of BYTE Magazine's BYTEmark benchmark program.
| name | result |
| integer: | 9.428 |
| floating point: | 19.336 |
| memory: | 11.683 |
The difference in time between the expected switch time and the time when a task is actually called by the scheduler is measured. For this test the RTAI UP scheduler is used.
RTAI README file| name | result |
| RTAI UP latency minimum: | -3121 ns |
| RTAI UP latency average: | -258 ns |
| RTAI UP latency maximum: | 12404 ns |
| RTAI UP latency runtime: | 6721 s |
