Sadly, the C64 is also quicker than Apple's iCloud website. Frequently, when I type a new note or a reminder, the lag between my pressing a key and character appearing on the screen is in several seconds. This is on a 4-core machine with 16 GB of RAM that's not doing anything else.
It really does perplex me that the iCloud website is as bad as it is. I'd almost think it was abandoned-ware except that Apple continues to update it. Their whole cloud offering (iTunes store, Apple Music, iCloud) needs a MASSIVE overhaul. Everything should be available via the web and on a modern accessible website.
I'd go as far as to say that they need a new point-person in charge of their Cloud Services because whoever is doing it now is completely out of touch. iTunes in particular is embarrassing, and I personally buy less stuff because I don't want to run it (instead use Vudu, Amazon Digital, etc).
iirc, icloud was written in sproutcore. version 2 of sproutcoure became ember which is now in version 3. there was no upgrade path from sproutcore 1 to ember, so likely its a case of needing a rewrite and that not being prioritized.
