I have the same exact card and I'm experiencing the same situation from client->unraid server. Was this resolved?

Oof. Spent a ton of time trying to figure out why I am getting asymmetric speeds with this -- I have the WISDPI 5GBe USB adapter connected to a Lincstation N1, 4x 4TB NVMEs in a stripe / ZFS. Plugged into a 10GBe switch that supports 5GB. My PC is using a 10GBe card, plugged into the same switch. Transferring data FROM the Lincstation/Unraid I am getting a bit over 400 MB/s, transferring from my PC to the Lincstation, I am seeing barely over 100 MB/s. There's no parity to worry about, etc. It's weird. Transfers to my other NAS hard (QNAP + Synology) both see speeds in excess of 500 MB/s. Any advice?
