My experiments - I have trying in μTorrent (3.3.1 build 30017) set all settings as it is in μTorrent (2.0 build 17920). - Then I have downloaded two torrents. As a result, at ninth minute I have "Disk overloaded 100%" problems. - After that, I have uploaded μTorrent (2.0 build 17920) with normal settings. As a result – 22 minutes of downloading without any "Disk overloaded 100%" problems.
