I wouldn't be at all surprised if that was too small for 30Mb+ connections.
If anyone with a fibre connection is bored enough to do some
experimentation, it would be interesting to see if some TCP tuning could
solve the problem.
I am happy to do some testing if you can advise how to do it! I am on
69Mb fibre.
I see this same issue on both my Windows 8 desktop and on my Windows
Home Server 2011 box.
I confess I wasn't even thinking of Windows. I don't have either of
those systems, but I'll guess that Windows 8 uses the same TCP
auto-tuning mechanism as Windows 7. The auto-tuning can supposedly
scale the receive window up to 16MB, which is ample. If auto-tuning is
switched off, the system uses a receive window fixed at 64K, which seems
likely to reduce throughput and cause more rtmpdump difficulties. OTOH,
maybe something about the auto-tuning is causing problems.
Basically, I'm clueless here. FWIW, here's a link I bookmarked for
Windows 7 that explained the auto-tuning setting:
