You're almost always put on Retx High when the SNRM target is lowered.
This has a lower throughput that Retx Low.
You can trick the DLM in to moving the line to Retx Low to get the throughput back up. This is done by capping the line.
There's a recent thread on this somewhere on the forum.
This is the best I can get on 79999/19999

https://www.speedtest.net/result/10095513220.pngSo there's very little difference, I've gone back slightly but what is noticeable is that my pings on speedtest.net now always seem to be around the 7/8 ms mark rather than the 9/10ms mark they used to be.
The other thing that's noticeable is that on other speedtests, such as Thinkbroadband, DSLReports, Fast.com etc, I'm seeing speeds of around 65-68Mbps whereas previously they were 71-73Mbps on the lower sync.
It's nothing too drastic of a drop off anyway so I'm not really fussed at the moment, but it would be nice to squeeze a little bit more out of it if possible but I'm not going to lose sleep over it.
What causes Retx to be on high and does it go to low if the line is stable enough? Just seems silly to increase sync speed if the actual throughput is going to be less.
