Yes, I have tried 100Hz, 250Hz. 100Hz works better than 250Hz.
CONFIG_PREEMPT_NONE, CONFIG_PREEMPT_VOLUNTARY, CONFIG_PREEMPT
It seem that, the only possible reason of performance loss from 2.4 to
2.6 is scheduler change.
How did you reach to this conclusion?
Try 100Hz + CONFIG_PREEMPT.I hope you must have tried this?
Do you still face problem?
Is a lot of IO involved in your applications?
