Parity PoA step duration

Question

I’m setting up a private blockchain using parity. I need to use PoA consensus with the maximum throughput possible. What do you recommend to set the stepDuration value to? Can we set it to a very low number to achieve a high transaction throughput or id does have a side effect?

Answer 1

What do you recommend to set the stepDuration value to?

In the discussion associated with Parity issue #9586, one of the Parity devs mentioned that block times of below 5 seconds are not recommended. I see that as being the lower limit to stepDuration. (Also note that you might want to use the --force-sealing option.)

(If you're experimenting with a high throughput, then this open issue might also be of use: #9393.)
