In theory this effectively doubles our throughput, though the initial results were almost negligibly better. Using a logic analyzer we see a pattern of 12 clocks, ~70ns delay, 4 clocks, ~310ns delay. So if we want to see further gains here then we'll probably need to tune AHB arbitration and utilization to eliminate bubbles/stalls when copying from APB DMA.
