 2. Allocating CPUs to the OAI nr-softmodem is done using the `--thread-pool` option. Allocating 4 CPUs is the minimal configuration but we recommend to allocate at least **8** CPUs. And they can be on a different socket as the DPDK threads.
 3. And to avoid kernel preempting these allocated CPUs, it is better to force the kernel to use un-allocated CPUs.
