Probably not. Knowing the speed-of-light round trip time to a network location gives you a bound on how much you can improve the performance of remote operations. For example, I'm in Austin, querying a database hosted in Amazon's us-east-1 data center ("Northern Virginia"). Call it 1000 miles away, 2000 mile round trip. You have: 2000 miles You want: millilightseconds 2000 miles = 10.736388 millilightseconds If I have a query that's taking < 1ms, no optimization of how that query is executed by the database can possibly improve the overall performance.
