µTorrent 3.3 gets a dramatic rewrite to its disk i/o, which means noticeable performance gains in multi-tasking.  For example, you can delete files from a torrent or move torrents to a new location, but without the usual slow-down in torrent downloading.  Or, download torrents to two different drives, but with the speed of downloading to a single drive. You'll notice gains at both low and high speeds, and whether you're writing to local disk, a RAID or a network drive.  You'll also experience improvements to the disk subsystem and rate limiter.
 
  
Next, we streamlined µTorrent features by eliminating underused and non-core features, including Apps and Find Content, the dual list view and the "getting started" tab.
  
Finally, we made a few bug fixes including a fix that noticeably speeds up the rendering of magnet links.
