Maybe I misunderstand his point, but isn't transferring data from Australia to the US or reverse always going to be slower due to the speed of light? What he's said doesn't negate the fact that he's only got one POP.
I'm not sure how many POPs they have so I do agree with that. I'm not shilling for B2 and have no affiliation with them. I've had good performance them but am US based.
My individual connections to B2 are slow (200-500 KB/s) coming from Europe but that's why the multi-threaded option makes B2 very usable.
Speed of light affects latency, not throughput. TCP works bad with large delays, that's why it's recommended to use several TCP connections to saturate the link.
Yeah, I can never remember how TCP window size + latency affects transfer speed but you're right.
Doesn't that destroy the value of B2 in that you're going to pay Amazon or whoever's egress costs?
Not if you're only egressing to B2 once to save and then egressing many times from B2 to serve.
In that case, consider packet, egress to B2 is free. They claim a good network, but I didn't test (yet).
You use the SJC1 option in packet.net to get the free ingress/egress. It's slowish single threaded but 100-200 megabit is easy with 4 threads.
