    Slow Single Thread TCP speed multithreaded is fine

    Hello ,
    I have a 60mbps unlimited connection that promises 60 down and 25 up
    when i test on speed test websites it shows that I get 58 down and 25 up to my isp but when I do the single mode test the speed comes down to 1-5 mbps.the same happens when testing to other servers outside my isp network .
    my single thread downloads are very slow too
    I get 200 kbps max and sometimes get 900 max .
    but when i download multithreaded I get good speed and i cam max out my line speed.
    it happens all the time.
    i have called my isp they run a test on multithreaded mode and tell me i have no problem.

    i have run some wireshark traces while running these tests and while doing normal downloads
    there are tons(2000+) dup ack and 500+ tcp retransmissions reported
    but odly enough pinging my local gateway i have no loss whatsoever
    i have also ran an mtr test and it reports loss only on the 3rd hop inside my isp network
    when i run mtr in tcp mode the latency fluctuates on the 3rd hop between 900ms and 7000ms
    idk if that is due to ratelimiting or something else

    below is the mtr result
    i have run all the test directly connected to the ethernet cable my isp provides
    my isp is lan ethernet based ...
    TCP mode MTR
