From my quick testing (mentioned earlier), I'm not seeing a significant difference on the typical systems we run (1 and 2 node). I'd find it hard to believe we missed a 13-24% win on all Linux systems anyway. Linux undergoes intense performance analysis, including checking for poor scheduling behavior. This sounds very much like a bug on 8 node NUMA systems. There's been lots of scheduling bugs over the years.
