You mean if AWS has 50ms data center latency than GCP has 5ms?

Google’s network is so fast, however, that this kind of multi-cloud might just be possible. To illustrate the difference in speeds, we ran a bandwidth benchmark in which we copied a single, 500 Mb file between two regions. It took 242 seconds on AWS at an average speed of 15 Mbit/s, and 15 seconds on GCE with an average speed of 300Mbit/s. GCE came out 20x faster.

What did you use to copy the file? If you used scp, your results are invalid and you must re-run the test again with a different protocol: you can't take advantage of large TCP window sizes with it because ssh uses a small, fixed send/receive buffer size. scp will penalize the performance of large transfers over high-latency links, even if the bandwidth between them is high.
