I've been using qbittorent for years now with a 3Mbps connection. My speeds never get much over 300Kbps. After a few years of this I decided to monitor my network and find I'm practically maxing out my bandwidth at 3Mbps when my qbittorrent speed is showing me around 300Kbps. I'm not finding an answer to this right off. Most discussions of overhead don't say anything about it being 10x the down speed. Can someone please enlighten me?
Thanks!

3mbps is 375KBps. **
You are getting 300KBps - roughly in qBittorrent - so you said.
The rest is called "TCP Overhead".

** Keep in mind that real speeds barely ever reach the "advertised speeds".
Your 3mbps might be 2.5, 2.75 or something in between.
http://speedtest.net ; http://speedof.me websites can measure your maximum speed.

Re: Overhead overboard
You probably have a 3 megabits/second DOWNLOAD connection...upload speed max may be a tiny fraction of that!
qBT's download speeds are measured in KiloBYTES/second. (...or possibly even KibiBYTES/second!)
300 KiloBYTES/second takes 2400 kilobits/second (2.4 megabits/second) before counting all the necessary overheads.
2.4 mbit/sec is pretty close to 3 mbit/sec...but that's not to say you don't have excessive overheads.
At minimum, overheads consume about 5% of the raw download speed...but with poor qBT settings and/or extremely busy torrent/s, overheads can be >25% of raw download speed.

Re: Overhead overboard
Thank you for the responses. I'm using etherape to monitor my network. I just don't understand why my network traffic is showing at close to 3Mbps while qb is showing downloads at about 300kbps. What is going on here? I've tried microtorrent briefly, but it seems to be similar. So why am I pulling 3Mbps while qp is showing 300kbps? I'm thinking there is a simply explanation or something to be learned. (And props to AT&T.... paying for 3Mbps and getting 3.5Mbps down, 300Kbps up. Feels lucky being in the sticks.) Bottom line, why is my download speed 10x less than my reported network speed? Any wisdom would be appreciated.

Re: Overhead overboard
Switeck... thank you for your input. This is really the heart of my confusion. Why is my net traffic 10x my qbittorrent dl speed? What's going on here? Thanks!

Its not, both applications are displaying the same thing in different units of measure.
qbittorrent measures in bytes etherape measures in bits
1 byte is 8 bits.
they are displayed as 1B/s and 1b/s
capital letters = bytes, little letters bits.
So when qbittorent reports 100KB/s etherape should report 800kb/s or 0.8mb/s, both these numbers show the same thing.
qbittorent downloading at exactly 300KB/s is 2472kb/s
Data recorded by etherape will likely be higher than that as qbittorrent doesnt report overhead in its speedgraph/display unless it is speed limited and told to include overhead.
You most likely would have other tasks in the background that use the internet aswell, DNS resolution services and such.
A 3megabit per second connection is very, very slow by todays standards.

Re: Overhead overboard
Peter, Switeck, Kitkat... Thank you. It makes sense now. I was comparing bits to bytes and didn't realize it. And Kitkat, 3Mbps isn't much, but just a few short years ago it was 300bps and a cassette for data storage.

That's improved by leaps and bounds then ;p
