What’s described in the post is the tech equivalent of supe-ing up a sports car and then driving it in rush hour traffic. It’s fun to geek out doing it, but practically in everyday use the difference will be negligible. Even with large file uploads and downloads, there’s a good chance that services won’t reach those throughputs end to end.
What’s telling is that the post shows screenshots and charts from artificial speed tests. No videos of the Dropbox client chugging away with throttled uploads.
