Percentage downloaded is less than sum of uploads

Post by anikey »

The situation goes like this (noticed twice):

There are two seeders in total, i have access to them. (One qbittorrent, and one i2p snark)
There appears a downloader using I2PSnark.

After some time, i sum the amount of bytes uploaded on the two seeds, and get value A.
Then i calculate the amount downloaded by the downloader, based on the percentage shown (formula: Torrent_Total_Size * Percentage / 100), and get value B.

On two separate times, i noticed that value A is much bigger than the value B (almost twice as much, i think).

What could this be? Could i2p snark be requesting the same pieces from two seeds simultaneously, and then throwing away one of them?

Another way of looking at it.
Assuming your clients are using the same router, which I don't know.
The downloader asks for piece 42 from the torrent.
Your router receives the request and forwards it to client #1 and client #2.
The router is not a switch. No. 1 and No. 2 do not coordinate with each other and both send piece 42.
But I'm just guessing here.

1. the seeds are on different routers

2. the i2p does not work like that, otherwise that'd be a big flaw (since different destinations are supposed to be isolated)

I think i'm noticing this again.
There is an i2psnark downloader.
I have 2 uploaders, i2psnark and qbittorrent. There are no other uploaders.

The downloader reports 1.9% progress (as seen on my i2psnark uploader).
My i2psnark uploader says it's uploaded (translated into %) 1.1%.
But when I add qbittorrent's upload to that, it becomes about 5%.
So, more than one half of the traffic gone somewhere.
