expecting to upgrade the PC to 10Gbps

upgrading from Cat5e to Cat8 did not improve thorughput.

yup that seems to be about limit of most usb 3.0 port on these devices, i have seen same, i don;t think is the driver or devices fault. need usb 3.1 gen1 to get 5g+

[CodeMichael]

That sounds about right.

FYI: Recent releases have included mitigations to reduce this logging.
