You pad each counter so that it's on a separate cache line. https://lmax-exchange.github.io/disruptor/ goes into detail on the false sharing problem.

I think reitzensteinm was referring to the actual data inside the ring. There is a false sharing problem there particularly for the MPMC type ring buffer like disruptor. The solution is to pad each data slot in addition to the read and write indices. I do this in my MPMC ring buffer queue: https://github.com/rigtorp/MPMCQueue/blob/master/include/rig...
