Global Upload Rate Limiting

• The Maximum upload rate field limits the maximum rate at which µTorrent will upload. Setting the value to 0 is equivalent to setting it to unlimited. This value is interpreted in KiB/s, so please enter it as such.
• The Alternate upload rate when not downloading field allows you to define an alternate upload rate when no torrent job is in downloading mode (only seeding). Other than the context in which it is active, this upload rate limit behaves exactly like the "Maximum upload rate" field. Unless you understand well the consequences of enabling this option, refrain from using it, as it might give the impression that µTorrent is not obeying the global maximum upload rate. This value is interpreted in KiB/s, so please enter it as such.

Global Download Rate Limiting

• The Maximum download rate field limits the maximum rate at which µTorrent will download. Setting the value to 0 is equivalent to setting it to unlimited. Note that download rate limiting is very unreliable, so you might see greater fluctuations in download speeds with this option set to anything other than 0, and µTorrent might not be able to limit the speeds to the specified amount either. This value is interpreted in KiB/s, so please enter it as such.

Number of Connections

• The Global maximum number of connections field defines the maximum number of connections that µTorrent can make at any given time in all active torrent jobs.
• The Maximum number of connected peers per torrent field defines the maximum number of peers that µTorrent can connect to at any given moment for each torrent job.
• The Number of upload slots per torrent field defines the maximum number of peers that µTorrent will upload to at any given moment for each torrent job.
• Use additional upload slots if upload speed < 90% tells µTorrent to open more upload slots if the current total upload speed is less than 90% of the global maximum upload rate.
