You're right that the network might be congested (noisy neighbors), but I
was asking if you were saturating your host's NIC with your own traffic.
Both could be a problem, but the latter is possible to investigate without
support from Amazon's technical support team.

Tim,
The NIC issue is a potential issue. We're trying to deploy via Fargate
where possible to shift the operational burden away from our developer
staff, so noisy neighbours is entirely possible, as is cross-AZ latency.
Touch wood, I seem to be in a place where throughput is at least as good as
e
Might the choke point be the NIC on the EC2 instance? If you run the
consumers for A and B on different EC2s, how does that throughput compare
to what you're seeing?
Also, I'd recommend you use JVisualVM or similar to capture a CPU sampling
(not profiling!) snapshot of your producer program to see
