Still not a hot idea. The IP packet size is ultimately limited by the Ethernet frame size, which is 1500 bytes practically everywhere. The article says, “A ton of favicon were bigger than 50k,” so it would take over 30 flawlessly delivered fragments to create this hypothetical “single” TCP segment. Any congestion anywhere between you and the server, and the segment does not succeed.
Though, I suspect stestagg meant IP packet. Less than 1.5 kB is just too small for most icons. The ubiquitous 32×32 Wordpress icon is just about small enough, and still sharp enough for Retina, but Amazon’s more detailed favicon is 2.8 kB, Y-Combinator’s icon is 6.5 kB, Apple’s 2-toned logo is 9.1 kB, and Microsoft’s 4 colored squares are an astonishing 17.1 kB.
On the other hand, like everything else outdated about it, Slashdot’s icon is a mere 668 bytes.
- J_Darnley 11y agoHow the hell big are these icons? 16x16 pixels uncompressed RGB is 768 bytes (1024 if you're using padding or alpha). I have just opened the page info for this reply page and am astonished to see a 256x256 image for the favicon. Who's utterly retarded idea was that? I guess that answers my first question. "Idiotically large" is the answer.
- Piskvorrr 11y agoGuess whose. (Starts with A, ends with -pple. Actually, that's not true either - .ICO has historically supported 256x256x16b for decades: there just wasn't anyone making them.) Of course, there's nothing intrinsically bad about high-resolution favicons - esp. given the current ultra-high-res displays. The size difference is only most marked in this specific use-case.
