Joking aside, as someone who runs their entire saas off a single bare metal server in Las Vegas, I have been toying with the idea of pushing some stuff to the edge. The reason being, sometimes those average load times are not giving you the real picture. If my average load time is 560ms per request because 90% of requests are 400ms and 10% are 2 full seconds, that might be a problem. Fixing those 10% requests and bringing them down in line with the rest would equate to an average speed up of only around 100ms.

However, I'm not yet sure a complicated edge deployment would actually fix the 10% problem.
