At that point, the instance managed about 8 HTTP requests per second, which roughly corresponds to one full business transaction (as a full business transaction is expected to involve withdrawing and depositing several coins).

At network latencies above 10 ms, the delay for executing a transaction is dominated by the network latency, as local processing virtually always takes less than 10 ms.
