But now it's that fast from almost everywhere on the planet, with nearly zero effort from the developer. We've been limited by light speed here, not compute.
The circumference of Earth at the equator is about 40,000 km and the speed of light is about 300,000 km/s. The appropriate division results in about 0.13 s.
That seems to track. The vast majority of requests won’t go half way around the Earth, so maybe halving that time at 0.06 seems like a reasonable target.
nah, most sites are fat enough that both bandwidth and compute is the limit.
Getting it closer can save you 50-150ms, but if whole load takes 1s+ that's minuscule
I get 381ms/401ms on first load and not the claimed ~30ms. I'm not really sure what the point is here though. CDNs and browser cache headers work? Static sites are fast to paint?
