it has its ups and downs, speed-wise
it was fast for months up until two days ago
e-hentai and danbooru have more images because rule34 doesn't allow anything that isn't porn (except for actual porn, that's not allowed, either)
also, e-hentai is terrible, and you should be ashamed for browsing it
as I write this, there are pictures of humanized apple with hairy balls and a giant penis sticking out of his underpants, a picture of a giant nintendo blue bird cumming on a wall, causing it to break, with the starfox fox holding on to his dick for dear life, while yoshi and lucario are climbing his leg, yoshi trying to catch some of his cum with his extended tongue
(I don't know nintendo characters very well)
oh, and this
