You might want to explain what you are doing, or what you are trying to achive. |

1ms-5ms latency in a user space process should be very easy to achieve on a fast machine. If you want 10s of micro-second latency your going to have tough time. |

It all depends on what your trying to do as to what the best strategy may be. |

|
33 |
If your writing C code see: |
34 |
|
35 |
man sched_setscheduler |
36 |
man setpriority(int |
37 |
|
38 |
check out sched.h |
39 |
|

remember real_time != fast |
