createBatch wrt to creation/second limit. createBatch is treated the same as create, and since createBatch accepts up to 100 instances, One would assume that the actual creation limit could increase to 100 × 100 = 10,000 creation/s when using createBatch. In my testing, regardless of using create or createBatch we can never go beyond 100 creation/s, although in some rare cases we hit 200 c/s, nevertheless far from 10,000 c/s as implied by the docs. For context we are on a paid plan.createBatch does not provide any real value other than syntactic sugar.
