In my 1.7 beta 1170 an all versions of µ I have used in the past. µTorrent suggested speed (actual uplink rate / suggested max upload rate)* 768 kbps = 72 kb/s 1000 kbps = 92 kb/s I'm not using the connection for anything other than torrents for 90% of the time and not much else is going on with my LAN. If I disable Auto I get up rates as high as 60 or more. I see how it is polling now (I got impatient and dropped the interval to 60 seconds, just to see how things work. I'll put it back to 600) [11:53:09] Uplink limit auto adjusted to 8.95 kB/s [11:54:09] Uplink limit auto adjusted to 7.66 kB/s [11:55:09] Uplink limit auto adjusted to 5.48 kB/s [11:56:09] Uplink limit auto adjusted to 7.25 kB/s [11:57:09] Uplink limit auto adjusted to 18.3 kB/s [11:58:09] Uplink limit auto adjusted to 43.9 kB/s [11:58:58] UPnP: Port 53268 is already mapped. Not re-mapping. [11:59:09] Uplink limit auto adjusted to 11.5 kB/s [12:00:09] Uplink limit auto adjusted to 32.0 kB/s [12:01:09] Uplink limit auto adjusted to 52.3 kB/s [12:02:09] Uplink limit auto adjusted to 55.4 kB/s [12:03:09] Uplink limit auto adjusted to 50.4 kB/s [12:04:09] Uplink limit auto adjusted to 54.7 kB/s [12:05:09] Uplink limit auto adjusted to 51.8 kB/s [12:06:09] Uplink limit auto adjusted to 55.7 kB/s It needs a more active (high upload demand) torrent I realize. I think I was getting the low 14kB/s b/c there wasn't a demand for any more than that at that instance. When I asked how it calculated I should have been more specific. I should have asked does it do some sort of bandwidth test outside of torrent activity or does it use torrent activity to check. I see now that it uncaps for bt.auto_ul_sample_window seconds and uses that for Automatic Upload speed calculation. If I go into Configuration during the poll window I'll see the rate set to 0, if I go during the non-poll window I see the calculated rate. Neat. *edit
