That's because without root, the application cannot raise its scheuling priority and it cannot change to realtime policy.
So the problem would appear to be that your networking *requires* ksoftirqd services to function. Either:
1) The driver is bust - its hard_start_xmit() function is failing frequently, and relying on ksoftirqd to get things done (I think; it's been a while). Or
2) Something is wrong with the ksoftirqd design. Or
3) Red Hat fiddled with ksoftirqd and broke it.
I'd be inclined to suspect 1).

That's a shame.
