Why is that happening? ----------------------------------------------------------------------------------------------------------------------------------------------------------------- 32-bit applications have limitations in terms of how much virtual memory is available, hence the number of hugepages they are able to allocate is also limited (1 GB per page size). If your system has a lot (>1 GB per page size) of hugepage memory, not all of it will be allocated. Due to hugepages typically being allocated on a local NUMA node, the hugepages allocation the application gets during the initialization depends on which NUMA node it is running on (the EAL does not affinitize cores until much later in the initialization process). -Sometimes, the Linux OS runs the Intel® DPDK application on a core that is located on a different NUMA node from Intel® DPDK master core and +Sometimes, the Linux OS runs the DPDK application on a core that is located on a different NUMA node from DPDK master core and therefore all the hugepages are allocated on the wrong socket.

Using the testpmd application as an example, the “burst” size can be set on the command line to a value of 16 (also the default value).
