Setting Ratio Groups In Rutorrent

1. Preface Unfortunately the rutorrent ratio groups are not very intuitive to use and also the corresponding documentation is incomplete. Therefore I made this small tutorial. The first part contains a detailed description about the underlying logic of ratio groups. However, if you are only interested in a particular (common) use case of a ratio group, such as seeding torrents to a specified ratio, you can skip to the example ratio groups that I listed in the second part. You can easily amend them to your own needs. 2. How do ratio groups work? Each ratio group consists of 4 different conditions ( Min,% / Max,% / UL,MB / Time,h ) and an action. Whether the action of a ratio group will be triggered depends on which conditions have been satisfied. Whether an individual condition has been satisfied (for a particular torrent) depends on either

• how much has been uploaded in percentage (Min,% and Max,%) or
• how much has been uploaded in MB (UL,MB) or
• how many hours the torrent has been seeded (Time,h)

For the sake of simplicity, these four conditions can be put in two different groups: The Min,% and UL,MB conditions (mandatory) These conditions are “packaged together”. That means only if both conditions have been satisfied, the action will be triggered. One condition alone doesn’t suffice. The Max,% and Time,h conditions (optional) Each of these condition is independend from all other conditions. That means, as soon as one of Max,% or Time,h is satisfied, the action will be triggered, regardless of whether the other conditions are satisfied or not. So these are hard limits. You can turn the Max,% condition off with “0” and the Time,h conditions with “-1”. The following table shows which combinations of satifsied conditions will trigger the selected action ✔= condition has been satisfied x = condition has not been satisfied or is turned off Note that there are limits to what you can do with ratio groups. For example, you cannot require a torrent to have both a minimum ratio and a minimum seed time. However, if you need such conditions you can use another tool such as rtcontrol. A ratio group / torrent size example Here is an example that shows after how much uploaded MB the action of a particular ratio group is triggered for torrents with different sizes. The Time condition has not been set (-1) for this example ratio group. Example ratio group 3. Ratio groups examples These are examples of commonly used ratio groups which you can easily amend to your own needs. Example 1 Torrents should stop always after reaching a 2.5 ratio If Min % = Max % then the UL,MB condition has (practically) no effect. The Time,h condition has to be turned off (-1). Alternatively you can specify the following conditions In this case the UL,MB condition (0 MB upload) is always satisfied. So as soon as the torrent reaches a 2.5 ratio the action will be triggered. Example 2 Torrents should stop always after 48 hours seeding regardless of how much (or little) has been uploaded Set the Min % condition to a very high value that is very unlikely to be reached by any torrent. This will (practically) turn both the Min % and the UL,MBcondition off. So the only remaining relevant condition is the Time,h condition. Example 3 Torrents should not longer seed than 48 hours and should not have a ratio greater than 1.5 The Time,h condition sets the maximum seed duration in hours. However, the action will be triggered before 48 hours have been passed if the torrent reaches a 1.5 ratio.
