Numa and vnuma

have a question regarding vNuma, NUMA.
Is there any advantage of enabling numa?
Noticed estop shows that some vm has 0 on numa column and some shows 1 and others -
Does this means that numa is enabled?

Yes, it's always recommended that NUMA is enabled on the HOST Server.

This is recommendations for a Dell R710, not sure what your host server is, but the same recommended to enable.

Generally, if your hardware supports Non-Uniform Memory Access (NUMA), you should enable it.
