i've proven before that I could tweak the rx/tx delay to reach 926mbit with Iperf, but once i started downloading something from a local HTTP server, i got a few Kbps
I noticed while I got 125 Mb/s from iperf with the adapter at 1000 I too was only getting a few Kbps by other means. I can't help but feel that is a clue to the nature of the problem, have been trying to remember other situations where I observed similar behavior. I remember similar behavior with a SonicWALL transparent DMZ several years ago, if I could only remember the details.
wget or curl might be good options. I also like to use mbuffer with -I and -O options a bit like netcat/nc but it can be set to load the file in memory to take storage access speed out of the equation.
speedtest-cli works pretty well for testing Internet speed, knowing that it may be limited by the speed of the connection itself.
