What is the most likely cause of TCP packet fastACKretransmits when testing with iperf3 on a small 5-7 node Linus AutoIP network running on a TI AM5728 board? Where and what setting should we check first? We are running both Ethernet ports of the AM5728 processor in a bridge configuration and running the iperf3 test from a 4GB RPi w/1Gb/sec Ethernet port through the 1st port of the TI board and out to a 2nd RPi on the 2nd TI board port.
Does anyone have a list of the standard latest greatest TCP protocol parameters, linux system control configuration and initialization settings?
Any help is appreciated.
