Processing samples in ARM

I have a rather simple question about ARM performance. I used iio_adi_xflow_check tool in libiio to test how much sampling rate the drivers can support. I observe I can buffer up samples even up to >=56MHz. However as soon as I add sample processing logic to the same code in the form of, let's say, a FOR loop calculating the ampltiude of samples, even at lowest samples rates (<=1MHz) I start getting overflows. I am not sure if this makes sense at all and is it viable to do any sort of baseband processing on ARM.
