the **spiciest** web performance leaderboard would rank saas company home pages making “blazingly fast”-esque claims 👀

put those INP and TBT scores in big bold letters 🌶️🌶️🌶️

It should be fair to post screenshots like this for companies that tout “the fastest frontends” on their home page—especially notable that this is *not* a temporary regression. It’s been like this for a long time—why is no one talking about it?

Here’s the source code between the doctype and the <title> for this site:

×91 external <script src>

This is not a nuanced point I’m making. We’re not debating the finer points of complicated web performance trade-offs. This is a very slow web site.

@zachleat What kind of intrigues me is that on 4G throttling and up, it really does feel fast, which I wasn’t expecting given all the server calls. HTTP/2 packing the calls into a single connection, I guess?

On Good 3G throttling and below, though, it really is deeply painful.

@Meyerweb The digital divide! I do think that there is a larger point worth making, as Vercel heavily invests in LLM automation of front-ends—automating this level of quality will only exacerbate the divide 😬

The other point I’d make is that Network throttling is only one piece. Testing on a slow device is another thing entirely.

@slightlyoff @zachleat More like treo.sh/itespeed/, amirite? HEEEYOOOOO
