If the number of CPU-cores per processor socket is increased in an ESXi physical host, then ESXi will require more time to complete certain tasks. (2006081)

Details

On some server platforms, the number of CPU-cores per processor socket that is visible to software can be adjusted through BIOS configuration options. As this number increases, ESXi running on such a server will require more time to complete the following tasks:
  1. Boot the host machine.
  2. Adding host to a HA cluster.
  3. Collecting vm-support diagnostic data.

The additional required time for the above tasks becomes more noticeable as the number of cores is increased to 8 or more per processor socket. Note that correct operation of ESXi is not impacted by this effect.

Solution

This issue is fixed in 4.1U2 release.
