audial Posted February 20, 2012 Report Share Posted February 20, 2012 I think this is a problem with the writing of the .DAT file on large torrents that you have only selected partial files on.I have opened UT with ~3-5 torrents going with download speed of about 1.1MB/sec. I then added a torrent at 100+Gb and selected only 12Gb of files inside it. As soon as did this the speed died. From what I see its because of the .DAT file.In the following picture you can see the file was created 2/20 at 1:18 pm. It is currenty 2:02 pm and the file is 10Mb in size:http://i44.tinypic.com/ezeql5.pngLooking at taskmanager I see nothing out of the ordinary in the way of memory usage or cpu usage:http://i44.tinypic.com/6th0fl.pngIf I look at disk performance I see the culprit:http://i39.tinypic.com/33yhr4m.pngNothing else is touching the disk. UT is only downloading at 10Kb/sec. The creation of this file is what is killing UT. As soon as it is done getting created UT will resume normal operations. The question is why does this file take so long to create? Its not using any CPU or bandwidth to create. Why is it writing at 5 Mb a second when its been doing this for approximately 40 minutes and the file size is only 10Mb?I invite you to do the same test, find a way to monitor your disk usage and you will see its the .DAT file UT creates that causes the HD strain and ultimately the disk overloaded.
