Isnt bsd's tcp stack single threaded?

• rwaksmunski 5y ago
  Netflix is pushing 400Gbit/s of TLS traffic per server with 60% CPU load. WhatsApp was doing millions of concurrent TCP connections per server. FreeBSD's networking has been multi-threaded for a long time now.

    Esp thanks to in-kernel TLS, which is fantastic.

  It has been multi-threaded since at least the early 2000s and most of the work for handling scaling beyond 32 cores was completed in 2012. https://www.cl.cam.ac.uk/teaching/1516/ConcDisSys/2015-ConcurrentSystems-1B-L8-handout.pdf https://www.cl.cam.ac.uk/teaching/1516/ConcDisSys/2015-Concu...

    Well, to be honest a whole lot has been done to FreeBSD network stack scalability quite recently (14-CURRENT), eg introduction of epoch(9) and the routing nexthop patches.

  It's multithreaded. I run FRR Routing punching 400gbit+ @ 75% CPU load on FreeBSD 12. On the same hardware, Debian fell over at 1.8gbit.

    How long ago did you compare them? I have been using FreeBSD for networking for awhile now but not at those levels

      6 months.
