The LMAX disruptor is a great data structure when you have threads bound to cores and most/all of them are uncontended. It has some terrible pathologies at the tails if you aren't using this pattern. Threads getting descheduled at bad times can really hurt.

SPSC ring buffers are going to be hard to beat for the system you are thinking of, and you can likely also implement work stealing using good old locks if you need it.
