Ah, I did not know Google was actively positioning SPDY as a good solution for mobile networks, I missed that.
I sort of want to defend that I counted the unreliableness of cellular as lack of bandwidth, but you're right if that's really wanted to say then I should have said it much differently. But do you really find it surprising that in the light of unreliability SPDY would not perform much better than plain HTTP?
To your third point: I wasn't saying everyone said it was a viable idea. Instead I say that only recently, with SCTP in HTML5 and QUIC people are beginning to think it might be a viable idea. But everyone has known for years that TCP just isn't suitable for the modern web, and if only we could, we would have substituted it with SCTP long ago.
- jsnell 13y agoThere are factors favoring SPDY, such as fewer roundtrips thanks to pipelining, or header compression removing the uplink as a bottleneck. There are factors favoring HTTP, such as being less vulnerable to head of line blocking, higher effective congestion/receive windows, and a smaller reduction on the effective congestion window from a single packet loss. Without testing, it's not at all obvious which set of benefits is actually more significant in the real world. But if I'd had to guess, I would have expected a reduction in roundtrips to be the dominant factor. So yes, I'm a bit surprised.
- tinco 13y agoAlright, makes sense :) Thanks for responding.
