Thanks Holden and Fooler.
The crux of the issue is that I cannot seem to get the supposed "receive load
balancing" feature of balance-alb working as I expect it -- I'm still only
getting 100MBps when simultaneous transfers from both clients to the server are
happening; I was expecting to see at least 160MBps if each clients are
transmitting to different NIC's in the server's bonded interfaces.

Mike,
The following links might help you. The first one is a detailed overview of
link aggregation. It uses round robin mode in the examples but the
explanations and tools might help. The second one is about copying large data
between server and host using various FOSS tools.

dont forget also to set your swtich mtu to 9000 as path mtu discovery
