Tor Relay on ARM server Marvell Armada 370/XP
Hello, i'm experimenting Tor setup on very cheap servers from scaleaway.com that run a quad-core ARM Marvell Armada 370/XP servers but have unlimited bandwidth. Those are Soc platform: http://natisbad.org/NAS2/refs/Marvell_ARMADA_370_SoC.pdf I saw no information on torproject mailing list about those SOC. I'm trying to push the limits and i saw that those have a crypto acceleration support: https://www.kernel.org/doc/Documentation/devicetree/bindings/crypto/marvell-... However with kernel 4.5.7 it does not really work and loading of marvel-cesa gives out error: [6.841862] marvell-cesa: probe of d0090000.crypto failed with error -22 :( I've only built latest Tor 0.2.9 with -O9 -mcpu=marvell-pj4 -mtune=xscale and the Tor Relay is at https://atlas.torproject.org/#details/82C63C5D61D17557B7C5D0E7FDC545A2B6B6B7... . Does someone have experienced optimizing and tuning Tor specifically on ARM processors to understand how far those could be optimized? -naif

the atom cpu suxx, install 2 instance, so you get around 100-120 mbit.
That's OVH, and Scaleway is Online.net. -- With respect, Roman

Volker - apart from not putting all eggs in the same basket (France as country and Online.net as ISP), but if you really wanna go there scaleway opened some cloud VPS in Amsterdam recently - same price far better performance, and yes as Markus wrote, they are very relaxed on Exits!

Do you run two Tor instances per machine? On platforms like these (with two or more cores, but each core being rather weak), you pretty much have to, if you want good resource utilization. Pin the 1st instance to cores 0,1, the second one to 2,3 using schedtool for better cache locality, and if you're already using schedtool, might as well mark the Tor processes as SCHED_BATCH. -- With respect, Roman
in my experience long time ago … arm suxx. I would switch to the 2 core atom, they suck too but no so bad as the arm there. Markus
