Indeed, first rule of realtime signal processing software writing is: If you can't finish the computation before next sample arrives, you are not real-time.
Throwing in additional tasks causing their own IRQ mask-out periods, and whatnot, just makes the scheduling delays worse.
Using e.g. RT-Linux can perhaps alleviate the non-rt scheduler's occasionally long latencies.
