Is there an Intel CPU scaling issue (non-linear performance), when using
more than 4 sockets Intel CPU with Linux?
If 'yes', then what are the background technical reasons for the non-linear
scaling beyond 4 sockets Intel CPU?
Understand each socket/chip can have many cores, for example 8
corresponding to 32 total cores.
