Thank you too Denis for your guidance in testing this appliance. The following is also addressed to all those interested: Just as a follow up, I performed some tests this morning using the old Devuan SD Card and a new NetBSD 9.2. The summary is: Devuan/Linux is hands down faster. NetBSD 9.2 is almost 50% faster than FreeBSD 13. While NetBSD's result is not stellar it's still better than the pitiful FreeBSD throughput. I will likely abandon using FreeBSD, but I should probably raise a bug report for this? I am not sure of the process for this or whether it's even wanted. That is, does FreeBSD care enough about little appliances like the Raspberry Pis to spend time fixing an obviously broken network driver/stack? Likewise, I guess, this applies to NetBSD. Anyway, thank you all for your assistance.
