14kB

August 24, 2022

I just read an interesting post discussing the benefits of keeping a webpage under 14 kilobytes due to the TCP slow-start algorithm:

Why your website should be under 14kb in size [endtimes.dev 2022]

The post explains that if you’re able to squeeze under that threshold, you can deliver your site in one round trip between the client and server. That can shave hundreds of millis off your load time.

What’s that, you ask? How many kilobytes is this page? Why, about 3! At 14kB for one round trip, that’s roughly 0.21 round trips. Because that’s how the internet works.
