All, thanks for the recommendations both on and off list.
It has been brought to my attention that a Mikrotik has a bandwidth speed test tool built into their operating system. Someone recommended a
https://mikrotik.com/product/hap_ac2 for MSRP of $69. The release notes of the newest version say:
!) speedtest - added "/tool speed-test" for ping latency, jitter, loss and TCP and UDP download, upload speed measurements (CLI only);
*) btest - added multithreading support for both UDP and TCP tests;
Do you think this device can push a full 1Gbps connection? It does have a quad core qualcom processor.
Besides mikrotik, I haven't found anything that doesn't require me to build a solution. Like OpenWRT with ipef3, or something like that.
Seems like a commercial solution would exist for this. I though CAF providers have to test bandwidth for the FCC randomly to get funding?
