For what it’s worth, you can buy the DirecTV DECA adapters for like $20 on Amazon. They’re actually just MoCA adapters, but they run at a lower frequency than regular MoCA so they don’t interfere with the DirecTV signal. They work fine by themselves.
The only downside is that they’re 100 Mbit/s.
That said, they really do give you a rock solid 100 Mbit/s.
If you need more bandwidth, I think Verizon sells a MoCA 2.5 adapter for like $60 which should give you GigE.
The 4ms of latency is a product of the MOCA protocol.
As a fully scheduled network, each packet must wait for a timeslot to send a reservation packet, wait for the schedule to be updated (map packet), and then wait for the actual scheduled time.
The reservation timeslots and mail packets are on a fixed schedule (approximately- there are cases where the timing changes if you have a poor link) with a consequence of an unloaded MOCA network having a transit time of ~2ms going from the master node, or ~2.5ms going anywhere else (master node transmit is faster since it gets to skip the reservation step. Times are averages, as the exact time depends on the alignment of the time of arrival to the scheduling period). Round- trip ping times should go up by roughly 4.5ms.
Under ideal conditions, it is possible to get 100Mbps UDP throughput on a pair of MoCA nodes (1518 byte packets). The physical media can support up to 110Mbps (MOCA 1.0), 140Mbps (MOCA 1.1) or 450Mbps (MOCA 2.0) user throughput per channel (up to 5 channels in MOCA 2.5), but that's shared bandwidth (all traffic summed together). Throughout will fall off in bad channels (minimum 40Mbps), or if you use smaller packets (higher scheduling requirements per packet) so YMMV
