I'm trying to setup Tor relay, just a middle, not an Exit.

I'm looking for the best configuration for the 100 mb / s. My current torrc is:

V3AuthoritativeDirectory 1
V3AuthVotingInterval 30 minutes

DisableAllSwap 1
AvoidDiskWrites 1

NumCPUs 4
DownloadExtraInfo 1
FetchUselessDescriptors 1

ORPort 9001
DirPort 9030 # what port to advertise for directory connections

RelayBandwidthRate  50 MB  # Throttle traffic to 100KB/s (800Kbps)
RelayBandwidthBurst 100 MB # But allow bursts up to 200KB/s (1600Kbps)
MaxAdvertisedBandwidth 100MB

ExitPolicy reject *:*

What is the best configuration options to prevent highload on the my workstation, and achieve as much cool for the Tor Network as possible?

I'm talking about:

  • Setup big bandwidths between Exits and Entries, and skip low. To prevent DDOS on the side of OS's IP addr table.

  • Setup Tor daemon in such way to prevent high load on the Disk sub-system, like Avoid Disk Writes, etc.

  • Keep highest and more relevancy Tor relays ( much more oldest ) in work with me.

Any ways to keep full 50 mb/s, the half of my real speed in job.

Currently, for the whole of week, my arm, tor console face give only:

flags: Fast, Running, V2Dir, Valid             exit policy: reject *:*

page 1 / 5 - m: menu, p: pause, h: page help, q: quit
Download (13.4 Kb/sec   - avg: 138.8 Kb/sec, total: 520.7 MB):     Upload (145.3 Kb/sec  - avg: 190.2 Kb/sec, total: 710.7 MB)

I don't know how, I don't know why, it doesn't take my bandwidth. Doesn't take more than 1mb/s. What is it? My OS is the last Ubuntu.

  • Note that 100MB means 100 megabytes. (Do you have gigabit down and up?) Your MaxAdvertizedBandwidth should not be higher than your RelayBandwidthRate.

As you are not setting up a directory authority, V3AuthoritativeDirectory V3AuthVotingInterval should not be set.

Tor will not put load on your disk. It will use bandwidth, CPU and memory. Disk usage is marginal in any cases.

For the rest, I suggest looking at the documentation on how to setup a high speed relay on Torservers.net wiki.
