[tor-relays] Unused Tor exit nodes capacity

[Josef 'veloc1ty' Stautner]

Hello Dirk,

mtr or downloading Ubuntu is not a valid task to check your network
connectivity.
Your server may has a connection speed of 1 GBit/s but that not the
traffic you can push the whole time. It depends on multiple factors.

For example:
I've a dedicated server in the netherlands with 1 GBit/s and my home
connection in Germany with 50 MBit/s. Most of the time I can download
with full speed from my server, but every day between 16:00 and 24:00
o'Clock the speed drops down to 100 kbyte/s. Why? The peering between
Level 3 and my ISP is out of capacity.

If you add Tor circuits there are even more bottlenecks.
You wrote:

"I pinned the ExitNode in my Client and downloaded an Ubuntu image.
Download was between 800 kbyte/s and 1 Mbyte/s. Not great"

My absolute highest speed over Tor was 7 MByte/s. So at least all 3
servers (Exit, Middle and Guard) had hight connections speeds. A speed
of 2-3 MByte/s is normal for me.

Long story short: Be happy that you run exit relays and don't care that
much about your traffic. Also think about network diversity.
