If my node is the only one seeding the file, accessing it via gateway.ipfs.io is slow but it's pretty obvious why; I'm the only provider.
So while for very public content IPFS is rather fast, if you share a couple files with a few friends, it's a bit slower.
Of course, this all depends on upload/download speeds, mine aren't stellar in both directions either.
Plus I'm rather certain that my ISP is throttling any kind of P2P traffic.
