> When benchmarking join operations via the {{SimpleBenchmark}} we produce 2 * {{numRecords}}, i.e, {{numRecords}} to topic1 and {{numRecords}} to topic2.
> The {{CountDownLatch}} in the {{foreach}} keeps processing until it has received {{numRecords}}. As this is the {{numRecords}} produced from the join, the size of each record will either be {{VALUE_SIZE}} or {{2 * VALUE_SIZE}}. The MB/s calculation doesn't take this into account.
