@BillA
I'm also sending (hardware generated) UDP packets to a PC. The best results are achieved if I have a point to point connection from hardware to PC with a separate network adapter just for the hardware.
For some Intel NICs (Pro 1000 series) you can increase the number of receive descriptors (see attached jpg).
This reduces in my case significant loss of packets.

Thanks Jens - this is very helpful. My 2nd NIC is an Intel-based device and also does have this RX (and TX) buffers setting. I will do some testing. I have a reliable UDP stream protocol and it should handle lots of data without loss but I was having to stall it at (go figure) every 256 packets (which is the Intel default and might be the Broadcom default which is my other NIC). I might still have to stall at this boundary but the stalls can be farther apart which is an improvement.
