draft
check if you got a numa-capable cpu and numa-enabled system or hypervisor
dmesg | grep -i numa lscpu | grep Thread lscpu | grep NUMA xl dmesg | grep -i numa
apt install numactl numatop
slackpkg install libpciaccess sbopkg -i numactl sbopkg -i hwloc
numactl --show hwloc-info hwloc-ls numatop
xen has a nice trick
cpupool-numa-split Splits up the machine into one CPU pool per NUMA node
