I have a 7mbps/768kbps ADSL2+ = connection through Fairpoint. The modem stats page shows its "attainable = rates" (kbps): 13330/1272 and Rates: 8271/1181. My SQM settings are: Download: 7000 (kbps) Upload: 925=20 Queue Disc: Cake/piece_of_cake.qos Link Layer: ATM/44 bytes overhead Advanced Options: default I have noticed that Win10 updates cause the network connection to become = unusable for other services/people, as if I had bufferbloat. But ping = times remain stable - they jump from ~20-22 msec unloaded to 40-50 msec. Experiments I have tried: - Setting download speed to 5000 makes the connection usable for other = people, although the ping times remain about the same (40-50 msec) - Setting the download speed to 8600 still keeps ping times down, but = that really harms other people's performance. - The link rates (download and upload) seem to track the SQM setting, = measured with both YAMon and the built-in real-time graphs. I get = ~6,000 kbps with a 7000 download setting, I got ~3,000kbps at the 5000 = setting. I get ~8500 kbps after setting download to 8600. - This doesn't seem to happen when I'm downloading other kinds of files = (I haven't tried torrenting files...) Downloading non-Win10 update files = seems to leave the connection in a fairly responsive state. Any thoughts? What other experiments should I make? Thanks! Rich=
