I have a script that compares Deluge stats with the tracker stats and here is a very typical example of its output:
Analysis is complicated since tracker stats sometimes have low resolution and are delayed by a few minutes, but the script compensates as well as possible (the columns are explained below the table)
Note:
- Items #10 and #12 have losses of 0.5 hours AND sizable upload credit (286 and 452 MB respectively); for those, the analysis is consistent over many samples and the loss is not a transient effect).
- Items #10 and #10 are RSS triggered torrents. No doubt the first 30 minutes of tracking is lost, which is usually the peak upload interval since seeding competition is the least then.
- Having 10 to 20% affected torrents is typical. I've not seen torrents lose more than one interval. Nor have I seen losses except immediately after creation. Only RSS triggered torrents have been affected in my observations.
