I've compiled the kernel with options PREEMTION I've tried rtprio I've tried sched_setscheduler(...scheduler=FIFO, priority=31...); Swapping is turned off.
I still get 250ms pausing in the tcp comm. Maybe it is the stack?! Is it losing frames perhaps? Any good ideas what to look for - someone. Regarding the HZ - My application never uses the cpu for more than 1ms or so before it blocks. So that should not be tha case. There are not many other processes and I have none of them running at an elevated priority/scheduler scheme. _______________________________________________________________________________________________________________ This e-mail communication (and any attachment/s) may contain confidential or privileged information and is intended only for the individual(s) or entity named above and to others who have been specifically authorized to receive it.
