The following section of the docs says: Ensure that each memory channel has at least one memory DIMM inserted, and that the memory size for each is at least 4GB. *Note*: this has one of the most direct effects on performance. https://doc.dpdk.org/guides/linux_gsg/nic_perf_intel_platform.html We are considering a project that has 2 dimm slots and will be using 16gb in one slot and leaving the other empty. Is it the empty slot that causes the performance hit? Thanks.
