How to increase the Advertised Bandwidth of Tor onion router (OR)?

Advertised bandwidth as reported by atlas and globe is really what is observed as of far. Your relay has only been up for four days, and as your relay proves its reliability and speed, advertised ...

What's a good RelayBandwidthRate?

The Tor Project now recommends at least 250 kilobytes/second each way to keep the level of service at least somewhat sane for users. Providing less bandwidth than that is actually a net drain on ...

What's a good RelayBandwidthRate?

There's basically always a shortage of bandwidth in the Tor network, so every amount of Bandwidth you can donate helps. Additionally, your relay usually serves more than one circuit at a time, so any ...

What does the heartbeat line in my torrc mean?

Those logs mean that you have transmitted 159 GB and received 157 GB as a total during the 5 days, which means you have sent only 31 GB in the period between the 2 log messages.

Can anybody explain the Advertised bandwidth, MaxAdvertisedBandwidth, Measured bandwidth, Bandwidth burst, RelayBandwidth rate?

I'll give it a try: BandwidthBurst: The maximum bandwidth of short spikes in network traffic. While Tor tries to use BandwidthRate on average, it may use this value for short bursts. It was advised ...

Relay bandwidth reporting frequency

Newer versions of Tor don't report data as accurately anymore, but globe hasn't been updated yet to deal with that. It's nothing to be concerned about. The change was introduced in 0.2.5.11 with the ...

How does Tor protect against flooding with artificially long circuits

The type of attack you are describing is a congestion attack. In theory, the simplest form of such an attack would be a general DoS on the Tor network. Taking things one step further, a congestion ...

What is the most appropriate kind of hardware to run a Tor relay on?

TL;DR: Tor does not make much use of more than one core, two cores (or one hyperthreaded core) per process is best a maximum of two Tor processes may register from a single IP, so a CPU with 4 cores ...

No it does not. (..and neither does the OR traffic.) The idea that 'traffic counts towards consensus weight' is not how it works. As I understand (from the linked document), the bandwidth is measured ...

Should I run fast Tor relay or a stable relay is fine?

This is a tough one. You don't have enough bandwidth to become a guard, so assuming you're not running an exit node, your node will only be used in the middle position. 500GB / month is about 100KB/s, ...

One relay with 4TB, with the relay using up the 4TB quota as fast as possible. Faster relays are more attractive to traffic, so the network is better off if you move that 4TB in a week then hibernate ...
