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
