Do you see the Tracker Status?
Proxy connect error: offline

You have set to use Proxy but it is not available (not running?)

Have been using uTorrent 1.7 beta quite sometimes, want to share the new feature "Automatice" upload rate with people.

Most people may already know, when set your upload rate to high may affect your download speed, or even others internet application, e.g. Web browsing.
But the concept of BT is sharing, the more your share, the more you get.
So, increase the upload speed always help your download speed. Usually we set the upload rate in a fix rate. Somtimes it is not efficient because of inconsistent network activity.
Or, if your Modem/Router is easily "hang" due to overload, this will help also (but not 100%).
So, to optimize your upload rate, utorrent has came out a new feature that "Automatic" adjust your upload rate. After some experience, I give the following suggestion for the setting.

Under "Connection", check the "Automatic" checkbox at the Upload setting.
Next go to "Advanced", set the following:

bt.auto_ul_interval 150
bt.auto_ul_max **** (see below)
bt.auto_ul_min 1024

Note
-----

bt.auto_ul_interval
value in seconds, default is 600, which means try to resample (measure) the network performance and adjust your rate accordingly.
For me, 10 minutes is too slow to response, I set it to 150 seconds.

bt.auto_ul_max
value in kilobytes/second
devide your ISP upload rate by 8.
eg. Streamyx Packages

Basic 384k (U: 128k) - 16
Basic 512k (U: 256k) - 32
Basic 1.0M (U: 384k) - 48

people may think that it is too high to make it to the maximum.
but don't worry, uTorrent will measure the speed, and most of the time, it will control under 80% of your Max.

bt.auto_ul_min
value in bytes/second
since Beta build 2740, the bt.auto_ul_min meaning has been changed.
"Change: bt.auto_ul_min no longer specifies smallest speed sample, but the lowest auto rate"
my previous recommend setting "1000" work not so well (don't know why). You can leave it to the default "8500" or my new recommend "1024".

Please share your experience after apply this setting.

Great to hear that.
But since Beta build 2740 had made some changes to bt.auto_ul_min, setting too low has weird result. Now recommend set it to at least 1500 or 2000.
