Hi,to saturate most of this bandwidth, you perhaps like to run multiple tor instances. Because mostly single core tor is cpu bottleneck.
2x tor per single IPv4 allowed for now.
in current c tor we only got minimal TLS options: # HardwareAccel HardwareAccel 0|1# If non-zero, try to use built-in (static) crypto hardware acceleration when
# available. Can not be changed while tor is running. (Default: 0) HardwareAccel 1 # AccelName AccelName __NAME__# When using OpenSSL hardware crypto acceleration attempt to load the dynamic # engine of this name. This must be used for any dynamic hardware engine. # Names can be verified with the openssl engine command. Can not be changed
# while tor is running. list em with: openssl engine -vv # AccelDir AccelDir __DIR__# Specify this option if using dynamic hardware acceleration and the engine # implementation library resides somewhere other than the OpenSSL default.
# Can not be changed while tor is running. Good luck with setting up acceleration if even possible in current versions? Andreas Bollhalder:
Hi allI have my first Tor relay up und running. It's currently installed on a little desktop computer with an Intel i5 9500T CPU. My Internet connection is 10Gb/s symetric. From this bandwidth, I would be able to spend a good part for supporting the Tor network.With that little machine, it seems that it would max out at somewhere at ~30 MBytes/s. For my definitive Tor relay hardware, I'm currently researching some options, which would be capable of handling Tor traffic at the rate of 200 to 300MBytes. Even it would be used nowadays, but who knows whats coming in the future and I hope this relay would last 5 years ore so.It looks to me, that with a normal CPU, it's impossible to reach my goal. But then I encountered, that Intel has the Quick Assist Technoloy (QAT) integrated in some of their products (ie. Atom C3xx8). This QAT can be used with OpenSSL as a hardware accelerator for encryption. There also exist dedicated PCIe cards with QAT (ie. Netgate CPIC-8955).Searching the Internet, I couldn't find any information if QAT would be helpful with Tor. But Tor uses the OpenSSL library and this can use the QAT acceleration. Is there anyone who has tried this und can share his expirience?Thanks in advance Andreas _______________________________________________ tor-relays mailing list tor-relays@lists.torproject.org https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-relays
