The Linux kernel will sort it out automatically. Deciding optimally which
programs get to run on which cores is the kernel's job.

It's also possible to pin programs to specific cores using "schedtool", but
that's more of an advanced tuning trick: not something you should need as the
first thing you do, but you could look into that if you get to the point when
both of them use 100% CPU, and you want to micro-optimize things a bit further.

It has 4 cores, and a single instance of Tor cannot utilize all of them. It
only uses one core and maybe 20-30% at most of another.

Ideally you would run 3-4 Tor instances on a 4-core machine (if RAM allows),
but the maximum allowed by the Tor authority servers is 2 per IPv4.

Any specific reason you have for running 2 instances of Tor on the same Raspi 
instead of one?

Re: [tor-relays] relays with dynamic IP - here Rasp2

[diffusae]

Hi!

That's from today:

rx  | tx  |total|   avg. rate
 +-+-+---
 today  6,26 GiB |5,21 GiB |   11,47 GiB |  1,27 Mbit/s


It's just a "low" bandwidth, but this depends on the ISP. It's a RPi-B
plus and it can't handle more than around 2000 TCP connections
simultaneously unless you are not using the normal CPU speed (700 MHz).

If there would be more bandwidth, than it should be higher.

Regards,

It is just 1 single Rasp2 - running 2 tor instances on 1 IP, details here

The Rasp2 is fairly unused, in memory and CPU - running on a German DSL - 
giving tested max. 7Mbit/s upload

There is no need for a Rasp3 under given condition - not even the Rasp2 is
