Setting TCP_WND and TCP_MSS to the same value is not a good idea if you
want to achieve high throughput as you effectively disable the sliding
window algorithm.
The timers are all running with the default values set up by the
Luminary library. All other communications, ARP, UDP and TCP, work
fine – it’s just this file transfer that is strange.
Could you maybe get a wireshark capture and attach it here (pcap format)
to try to trace the packets in the stack? Maybe the delayed ACK
mechanism interferes with the used protocol...
