Or, you know, you could just run one tor daemon per core as has been suggested. Thanks for your understanding and your patience with us while we work on this and a couple other slightly difficult and pressing engineering problems. Christian Dietrich: > I've got arround 200 mbits with an Intel Xeo

I've added "numCPUs 2" to torrc and restarted via the init script. It does not seem to have made a difference. I presume that's where/how it should have been added? The FAQ says it doesn't do multi-core well. Seems unfortunate - multi-core is everywhere, now. On 01/24/2014 07:41 PM, Sebast

Re: [tor-relays] Would be good if Tor were more multithreaded.

The NumCPUs option only causes OnionSkins (circuit creation requests) to be processed on additional threads. This is only a portion of the CPU cost of a tor relay (doesn't include TLS, circuit-level AES, packet handling/memory operations, etc), and now that the network is switching over to the cons

Sebastian, Jobiwan, Moritz, thanks for your responses! It seems like the machine might be able to utilize its 100 Mbit link with only one process, but running two processes is definitely a safe bet. So I guess I'll do that. Best regards, Alexander --- PGP Key: 0xC55A356B | https://dietrich.cx

Hi Alexander A Tor daemon running with numCPU2s is better than a single daermon on each core because there is less "overhead". You can also get a great boost by enabling AES-NI hardware encryption if you don't have it already ... This is the best docu available afaik: https://www.torserver
