I don't see it. The number seems to be around 3 million, corresponding to a buffer size of ~2.5 MB, doesn't it?

Oh yeah, now that you mention it, there's more wrong on the page than I thought. You're right, it does correspond to about 2.5MB plus a 15% roundup. However, that's 10 times too small. It should be 25MB plus the round up.
If you follow the link on the page to the Cameron Sparr post, you'll see it says "It is highly recommended that you increase these OS limits to at least 25MB before trying to run UDP traffic to your server. 25MB is just a recommendation."
The non-BSD values on your page are a factor of too small as well. Sparr's recommendation for them is 26214400.
I noticed this when I copy & pasted the values from the quic-go page to my macbook and got a response that showed that the buffer size had gotten smaller. Turns out the default is kern.ipc.maxsockbuf: 8388608

We recently bumped buffer sizes in #4455.
