Re: [tor-relays] What kind of hardware do I need for my relay

[Andy Weber]

Hi,

I added 0x3d006 and 0x3d007 on a Dedibox XC
(https://www.online.net/fr/serveur-dedie#perso) just a week ago. They
offer 1 GBps both directions unmetered (+2,5 Gbps to the internal
network) for very little money on an Intel Atom C2750 (with AES-NI,
cpubenchmark.net score: 3929, single-thread rating: 579) with 16GB of
RAM and 1TB of HDD (or 250GB SSD if you manage to grab one of those).
Those nodes are abviously still picking up speed but right now they're
already doing 8.73 and 5.6MB/s after only 8 days with both Tor processes
eating on avg. around 15% of CPU. At 100% load per instance that would
give me approx. 2 x 45 MB/s when running on full speed - altogether
~720Mbps which would barely be filling the pipe.

So on this particular machine 45MB/s per core (with a 579 points
single-thread rating) should add up to ~13 single-thread points being 1
MB/s. That may of course vary depending on your CPU architecture and
network but it just may be something to base your calculations on. Some
of my other nodes (0x3d001 and 0x3d002) are running on an E3-1245 v2 and
they both do around 40MB/s, single-thread score for that CPU is 1996
which would equal a bit less than 50 points per 1 MB/s. But on those
instances it's rather the pipe that's the limiting factor, I can't push
much more than 80MB/s there any direction any time of the day. Well,
check the stats for yourself and do your own calculations:
https://atlas.torproject.org/#search/0x3d00 (0x3d003 is running on an
E3-1230 v2 and 0x3d004 and 005 are an i7 6700K).

*tl;dr:* On average around 25~30 single-thread points for your CPU on
cpubenchmark.net should give you +/- 1MB/s of sustainable Tor traffic.

Hey Farid,
Have you found an interesting low cost hardware since this last message ?
Sometimes I try to look for it, but there's a lot of little cards like
RPi, Banana... sadly I think it has not enough CPU power to play with a
lot of Tor traffic :s

On the torserver webpage, there's a command line to know if the cpu has
AES-NI acceleration.

cat /proc/cpuinfo | grep aes

For fun, I've tried on a laptop with Intel Core 2 Duo... no result shown
after this command.
So sadly this laptop will not be enough strong to have fun with this
kind of crypto... it's sad because it's not burning a lot of watts!

Re: [tor-relays] What kind of hardware do I need for my relay

[Farid Joubbi]

OK. I thought from the beginning that my relay running the Banana Pi would be 
capable of handling more traffic.
I have asked about it before, and got some really good answers.
I still can't completely explain why it does not handle more.
You can read about it here:
https://lists.torproject.org/pipermail/tor-relays/2016-September/010142.html

The relay is still up, you can see a link to atlas on that thread.
It has become a bit unstable lately and stops responding for some unknown 
reason.
I don't know why the amount of traffic about doubled in October.

I ran a relay on a Intel NUC on OpenBSD for a few months.
The traffic through that relay was very very low compared with my expectations.
I got an answer from this list that the OS is most probably the one to blame.
It has been shown that OpenBSD has a lower throughput of Tor traffic compared 
with FreeBSD and Linux.
I have not found an answer to why it is so.
Still I think it's a good thing for Tor to have the diversity of different OSes 
running the network.

I don't understand why Atlas shows the amount of traffic in Bytes instead of 
bits.
I just know that it is so and that it has confused more than one person in the 
past.

So in conclusion, I'm more confused now than I ever was before ;-)

No, but it can be used to roughly judge what the hardware is capable of.
It doesn't help to throw more hardware at a node when it just doesn't get
more traffic from the network.

Last year one of my node's traffic increased about tenfold
in the span of a month, without reason or rhyme as seen in

Re: [tor-relays] What kind of hardware do I need for my relay

[Olaf Grimm]

Ok, N3050 cpu count was my mistake. It are 2 cores. It is a hand-size
mini pc (ZOTAC 323 nano). It act as a middle node.


Now checked: The cpu load is ~15% with 1184 connected relays! (home
connection with 10MBit/s; actual modem usage: 5MBit/s upload average,
8MBit/s peak. Downstream equal upstream.

(Sorry for wrong values before with an upload of 1MBit/s. I had
forgotten my line upgrade some months ago.)


Relay fingerprint:E9A31E7EFF7A062AA67DA601CC70605AACF9F385
Relay external address:91.48.47.161
Total traffic (read/written):260.18 GB/263.10 GB
Connected relays(1184)


ATLAS says 200 kByte/s (graph) >> ~2MBit/s   Where is the mistake? I
expect a lot more. The wrong value is stable over weeks.


One of my external VPS server:

Incoming / outgoing ~30MBit/s with a 100MBit/s connection

ATLAS says 4MByte/s (graph)

ARM display 40% cpu load with 5% for ARM itself.

RAM 4GB, 1 virtual core, XEON, ?? GHz


My confusion: ATLAS display MByte/s, not MBit/s. Every time I traped in
this. It is a technical agreement, that serial lines are rated in Bit/s,
not Bytes/s. It would be nice to change this in ATLAS.


I hope now my values are clearer than before.

This sounds wrong. VIA Nano 1.6GHz, a single core laptop CPU from 2011, can
sustain about 40+40 Mbit (WITHOUT utilizing the crypto acceleration).

The Celeron N3050 has two cores and supports AES-NI, and if OpenBSD seriously
doesn't (which I doubt), then swap out OpenBSD.

With two cores you could also run 2 instances of Tor for more efficient CPU
use. I would expect both cores stay at sub-50% CPU use while the entire thing
is capping out into the full 100+100 Mbit.

That said, when did you measure the speed, and are you aware of
https://blog.torproject.org/blog/lifecycle-of-a-new-relay ?

Another possibility, maybe your ISP only provides "up to 100 Mbit" and is
shaping certain types, patterns or amounts of traffic use.

I do mean Megabits.
I have learned a long time ago that Tor traffic throughput can't be compared 
with ssh.
Tor needs to sustain the traffic amount for a long period of time with many 
variables affecting the measured bandwidth.

Also I would prefer to run OpenBSD, which does not have support for AES-NI by 
design (last time I checked).

Which is a good thing, by the way. Tor traffic is bursty, so when your
tor node actually saturating the link it means that the latency goes up,
which means poor user experience. (This is generally so in networks -
full pipes are bad.)

Re: [tor-relays] What kind of hardware do I need for my relay

[Olaf Grimm]

More is better. Here my values at home:

Intel N3050 4x 1.6 GHz in an internal firewall with external Tor
application. Internet connection download 50 MBit/s, Upload 10 MBit/s.

Internal LAN performance: 90 MBit/s

My own downloads are near 50 MBit/s (less time, most time 20...30MBit/s);

Uploads near 8 MBit/s in peaks; Never theoretical limit reached.

My personal usage drives the internet line to full power, but Tor as my
MIDDLE RELAY doesn't use the full internet line power. It is dependend
from the cabability of the guard/exit partners. Cpu load is less then
20%. The traffic is symmetrical IN/OUT.

My other external middel nodes doesn't use the full internet line power
too. The cpu load is less then 10%. The hardware ist a single VPS cpu
3GHz with 512 GB RAM. This was the minimum of provider offer.

Take a look on

https://atlas.torproject.org/#search/node49

node49 is my home middle node. node49a/b are external VPS with 100MBit
connections. The usage is about 5-10 MBit/s. Cpu load about 10% in peak.

Re: [tor-relays] What kind of hardware do I need for my relay

[tor]

Agreed you won't need much to max out a 100 Mbps connection.

I have a few relays in the ~ 200 Mbps ballpark running on single core VPS 
instances. The underlying hardware is based on Intel Xeon E5-2650L.

CPUs with AES-NI help. 2 cores may offer marginal improvement. More than 2 
cores isn't going to help at all. Tor still isn't optimized for it.

If running on Linux or Unix there are a lot of optimizations to be done. For 
Linux, I'd start here: https://www.torservers.net/wiki/setup/server and look at 
the "High Bandwidth Tweaks" section.___

Re: [tor-relays] What kind of hardware do I need for my relay

[Farid Joubbi]

I'm a little surprised that this kind of question is not documented anywhere, 
or at least I have not been able to find it.

I have only found others asking the same question as me without getting a good 
answer.

There was a quite exhaustive discussion seven years ago:

https://lists.torproject.org/pipermail/tor-relays/2010-August/000164.html

I am prepared to pay a pile of cash for a computer that I will dedicate to run 
a relay.

I have a 100 Mbit/s symmetric connection.

What should I buy?

I don't want to buy something that has a too slow CPU that is not able to push 
enough traffic, but I also don't want to overkill and get a huge electricity 
bill.


Sebastian,

How much CPU does your relay have/use?

Hi Farid,

I'm running my Guard / Relay on a VPS with only one core and 512MB RAM. Its 
also hosting a blog, my own mailserver and is member of pool.ntp.org

I haven't encountered any problems so far. It's also connected via 100MBit/sec

You can see the stats here: 
https://atlas.torproject.org/#details/F381D6294A93A0078B76D0DCA332133CF5C8F687 
I experimented a bit in the last weeks with being a bridge, but I now I'm back 
as a Relay... therefore the performance charts are not as high as they have 
been at the end of last year.

Hello,


I have been running low powered middle relays for a few years.

Now I think it's time for a small upgrade.

I haven't looked at computer hardware for a long time.

What is the cheapest and most power efficient CPU/motherboard that can saturate 
100 Mbit/s as a Tor relay?


Thanks.

[tor-relays] What kind of hardware do I need for my relay

[Farid Joubbi]

Hello,


I have been running low powered middle relays for a few years.

Now I think it's time for a small upgrade.

I haven't looked at computer hardware for a long time.

What is the cheapest and most power efficient CPU/motherboard that can saturate 
100 Mbit/s as a Tor relay?


Thanks.
