SPDK uses a busy-polling reactor model where the master reactor handles both I/O polling and management RPCs. When only a single core is assigned, heavy I/O workloads can delay or starve RPC processing, resulting in increased latency, timeout events, and operational instability. Assigning 2 or more cores allows I/O and management tasks to run on separate reactors, improving responsiveness and operational stability.
