You can have microsecond updated, once the connection is established you can stream. Regardless of your latency.

Say your ping is 100 (units are irrelevant here). It will take you 100 before you see your first byte but if the server is sending updates down that connection you will have data at whatever rate the server can send data. Say the server sends every 10.

Then you will have updates on the client at 100 110 120 130 etc.

That's still 100 irrelevant units later than the server sent the update. This is like saying the first byte of the packet takes 100ms to arrive but the subsequent bytes in the packet are instant!

It's not quite right. You'll never have updates in microseconds even if your ping is, say, 7ms.

At best you can be ~2-4x as fast as long polling on HTTP/1 -- an order of magnitude is a ridiculous statement.

You're right! 200-400% faster is so useless.
