The no-shconf should have no performance impacts, the flag only adjusts<br>
whether the basic DPDK configuration information (generally only used at<br>
init time), giving details of hugepage mappings etc, is stored in shared<br>
memory or in memory local to the process. Using the former allows sharing<br>
among multiple processes, but could lead to name conflicts between<br>
processes unless --file-prefix EAL argument is also used. Using the latter,<br>
local memory, disables multi-process support, but is probably safer and<br>
easier if MP support is unnecessary.<br>
