Description of problem: Sometimes yum shows negative downloading speed. Version-Release number of selected component (if applicable): 3.4.3-104.fc19 How reproducible: I don't know guaranteed way to reproduce it, but from what I noticed it is more likely to get it on slow/laggy connections. The most of times I observed it were when I used EvDO/CDMA connection (maximal speed - 3.1 Mbits/s, actual speed varies hugely depending on signal strength and weather on Mars). With my fast 25 Mbit/s connection, it is very rare thing but I still saw it a few times. Steps to Reproduce: 1. Connect to slow Internet (recommended, but can occur with fast one too) 2. yum update (or yum install a-lot-of-huge-things) 3. Wait and watch... Wait and watch... 4. And then it will happen. Or not. Usually it lasts only a few seconds, but sometimes yum drops connection with mirror because of it (more than 60 seconds with speed <1000b/s) Actual results: Negative downloading speed. Expected results: Actual or at least positive downloading speed. Additional info: ...
I'll look at the rate estimator code if there's some obvious bug. It does simple temporal averaging and if every partial input is >=0 the output should never be negative. Probably the input to the estimator was garbage (negative size or time deltas). > but sometimes yum drops connection with mirror because of it (more than 60 seconds with speed <1000b/s) That's unrelated. The displayed download speed is UI thing *only*. Yum does not close the connection, curl does (it does no averaging, speed has to be below the limit for the whole period). If you don't want this, set "minrate=100" or so in yum.conf
