There's a way of reducing latency on the MOD Dwarf which employs the parallel processing capability of the unit - basically a signal goes into one effect (or chain of effects), the processing of which is carried out by one processor, then passed via something called Portal to the next effect (or chain of effects) which is processed by a second processor, so the overall latency, instead of being the sum of all the latencies in the chain, is just the greater of the two latencies on the signal chain plus a small overhead (I'm not sure if it's referred to as the critical path, but if you've ever played with Gantt charts, it's the critical path equivalent).
