The Pieces tab displays each piece currently being downloaded by µTorrent. If a piece is selected, then holding Shift on the keyboard while right-clicking on the pieces list will display a context menu with the option, "Log piece info...." When selected, debug information is added to the Logger tab for the currently-highlighted piece. The following is a description of each column:
- # is the piece's number in the .torrent file.
- # of Blocks is the number of 16 KiB blocks that compose that single piece.
- Availability is the number of times this piece is seen completed within the group of peers you are currently connected to.
- Blocks
is the graphical progress bar for the piece. You'll notice that there
are different colors displayed for different blocks. They are as
follows:
- Dark blue means the data has been downloaded and written to disk.
- Medium blue means the data has been downloaded, but remains in the cache in memory, unwritten to disk.
- Light blue means the data has been requested from a single peer.
- Green means the data has been requested from multiple peers. Blocks only turn green during endgame mode.
- White means the data is is available in the swarm, but has not yet been downloaded.
- Completed is the number of blocks completed in the piece.
- Mode is the general evaluation of the speed at which the piece is being transferred by the peer. A piece's mode can be either fast, medium, or slow. µTorrent uses this evaluation to determine whether a piece should be taken from fast peers or slow seeds. This is meant to try to prevent situations where a slow seed sends the same piece as a fast peer. Instead of allowing that to happen, µTorrent attempts to have the slower seed send another piece, possibly something that might be rarer in the swarm.
- Priority shows the priority µTorrent has assigned the piece based on the priority of the file(s) it belongs to. If the piece belongs to multiple files, then it is assigned the highest priority of the files it belongs to. If a piece passes the criteria for being given higher priority by bt.prio_first_last_piece (assuming the option is enabled), and the piece's priority is not skipped, then piece's priority is elevated by one priority level.
- Size is the size of the piece.
