Josh Thompson commented on VCL-1136:
------------------------------------
The code just committed has a hard coded threshold of 32 cores to determine if
NUMA checks and configuration are done. This probably should be pulled out to
be more easily configured by users such as adding it to vcld.conf. Another
option would be storing it in the variable table so it could be configured from
the web site. Adding to vcld.conf would allow it to be configured per
management node. Adding it to the web site would make it global but slightly
easier to configure.
