For comparison, Amazon.com and NASDAQ likely process no more than 10,000 orders/trades per second even during peak workloads. I haven’t worked with NASDAQ stream directly, but knowing how fast equities tick I find this “10,000 orders/sec” estimate quite low. Not to mention that 10ms delay in confirming an order would be really terrible.
