Nop. It's that a better solution would still be using multiple Redis instances on each physical server. Trying to support multi-threads in the storage engine requires complex synchronization implementation. Sharing nothing between each small instance achieves higher performance and is a lot simpler. Also, FULL SYNC between masters and replicas can be uncontrollable. And smaller memory size for each instance alleviates the performance impact from FULL SYNC.

not to mention, multiple instances follows the indistry direction in horizontal scalability. Common advice when building for k8s style cloud environments is to target single core, n instances, to maximize scaling flexibility and atomicity.
