Also a great tool to measure pure HTTP / HTTP download thus line speed: axel

Code: Select all

$ axel http://cdimage.ubuntu.com/daily-live/current/kinetic-desktop-amd64.iso

[ 18%]  .......... .......... .......... .......... ..........  [60356,9KB/s]
[ 18%]  .......... .......... .......... .......... ..........  [60359,4KB/s]
[ 18%]  .......... .......... .......... .......... ..........  [60362,2KB/s]
[ 18%]  .......... .......... .......... .......... ..........  [60361,8KB/s]
[ 18%]  .......... .......... .......... .......... ..........  [60357,9KB/s]
[ 18%]  .......... .......... .......... .......... ..........  [60357,9KB/s]
[ 18%]  .......... .......... .......... .......... ..........  [60358,4KB/s]
[ 18%]  .......... .......... .......... .......... ..........  [60357,5KB/s]
[ 18%]  .......... .......... .......... .......... ..........  [60360,4KB/s]
[ 18%]  .......... .......... .......... .......... ..........  [60360,3KB/s]
[ 18%]  .......... .......... .......... .......... ..........  [60363,1KB/s]
[ 18%]  .......... .......... .......... .......... ..........  [60360,2KB/s]
[ 18%]  .......... .......... .......... .......... ..........  [60361,6KB/s]
[ 18%]  .......... .......... .......... .......... ..........  [60360,2KB/s]
[ 18%]  .......... .......... .......... .......... ..........  [60362,6KB/s]
[ 18%]  .......... .......... .......... .......... ..........  [60359,5KB/s]

So about 60 MB/s, about 480 Mbps nett, so about 500 Mbps linespeed.

Or less output: print each 5000th line:

Code: Select all

$ axel http://cdimage.ubuntu.com/daily-live/current/kinetic-desktop-amd64.iso | awk 'NR % 5000 == 0'
[  6%]  .......... .......... .......... .......... ..........  [65324,1KB/s]
[ 13%]  .......... .......... .......... .......... ..........  [64452,8KB/s]
[ 20%]  .......... .......... .......... .......... ..........  [64262,1KB/s]
[ 26%]  .......... .......... .......... .......... ..........  [64232,9KB/s]
[ 33%]  .......... .......... .......... .......... ..........  [63914,5KB/s]
[ 40%]  .......... .......... .......... .......... ..........  [64144,9KB/s]
[ 47%]  .......... .......... .......... .......... ..........  [54008,8KB/s]
[ 53%]  .......... .......... .......... .......... ..........  [51067,9KB/s]
Other URL

Code: Select all

$ axel https://speed.hetzner.de/1GB.bin  | awk 'NR % 5000 == 0'
[ 24%]  .......... .......... .......... .......... ..........  [59191,5KB/s]
[ 48%]  .......... .......... .......... .......... ..........  [63264,6KB/s]

Cool. I love it when a plan comes together.

About switching to fast ethernet instead of gigabit ethern due to switches/cables/etc: the same now and then happens to me. For no apparant reason. Very annoying. I'm sure it can't be the 9 euro ethernet switch nor the ethernet cable I patched together myself. ;)

Why is no one mentioning to check Config > General > Tuning < Maximum line speed? That was my issue.

My internet bandwidth was ~29MB/s but I was only getting exactly 10MB/s. Changed the setting to 30MB/s – fixed!

Can't post a link to the wiki article, but Google, "SABnzbd High speed Downloading".

Because that's a bit too obvious... It's also shown to you in the speed limit slider what you configured as maximum.

It's also something you configure yourself, not set by us.
