TS-3477: Change the default thread affinity to 1 (NUMA node)
> Determine thread affinity defaults automatically based on hwloc
> ---------------------------------------------------------------
>
> Key: TS-3477
> URL: https://issues.apache.org/jira/browse/TS-3477
> Project: Traffic Server
> Issue Type: Improvement
> Components: Configuration
> Reporter: Sudheer Vinukonda
> Assignee: Phil Sorber
> Fix For: 6.0.0
>
>
> {{proxy.config.exec_thread.affinity}} allows to configure the thread affinity
> depending on the system configuration.
> https://docs.trafficserver.apache.org/en/latest/reference/configuration/records.config.en.html#proxy-config-exec-thread-affinity
> It would be nice if ATS can default automatically to the appropriate setting
> based on the configuration from hwloc to reduce unnecessary complexity for an
> end user configuring ATS.
> [~zwoop] suggests to default to {{2 - assign threads to sockets}}, if there's
> more than one NUMA node and {{0 - assign threads to machine}}, if not.

> {code}

> 8:38 if you have more than one NUMA node, probably default to 2, otherwise,
> default to 0
> {code}
