-------------------------------------
Summary: 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
{{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.

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