I am confused, you restricted the egress speed to 10 Kbps and wonder why performance was less than satisfactory? :) I you just want to be sure that you are not limited by bloated buffers restricting the bandwidth to 50% of link rates (or even rougher of the transfer estates of betterspeedtest.sh) should be a good starting point. At that rate you will only be able to send 6.66666666667 full sized packets per second each taking 150 ms. > > Yes I have DSL line (VDSL2 as I've read ISP info), Hard to believe that any ISP will give you VDSL2 at around 4M/512K as at that speed you are either so far away from the DSLAM that VDSL2 is not any better than ADSL, probably worse, or you link is faster and your ISP throttles your bandwidth due to contract. But you could run the attached script overnight from a linux or macosx machine to test whether your link used ATM encapsulation. A link using ATM will really improve by specifying the correct link layer adjustments and overhead, VDSL2 not so much. If you run this script I am happy to help you analyze it to figure out whether your link uses ATM or not. Oh by the way most ISP modems/routers have a web page that offers (technical) information about the link it would be great if you could find and post that.
