One thought on - Best Kernel For Asterisk

  • Hello,

    I prefer to work with the standard kernel from the distro (using debian)
    for security reasons, unless there is a team in the company with very good kernel tuning knowledge. Probably one can squeeze some more performances with a custom kernel build, but in long time that typically becomes a maintenance nightmare.

    If needed, you can instead aim for horizontal scaling by deploying a farm of Asterisk systems with a sip proxy load balancer in front of it
    (well, I could be a bit biased, because I do work mostly with the kamailio sip proxy). Anyhow, to cut it straight, standard distro kernel worked fine for the deployments I was involved in.

    Cheers, Daniel
