Hi Kevin,

Hi Kevin,
It wasn't done with slob.. I used my cputoolkit but I have a detailed comparison of both of the tools here http://goo.gl/nR9Yy
And although the workloads of both tools are different they both showed that once the CPU intensive load gets past the core count (real cpu cores) you only get about 20-30% LIO/sec increase up to the max # of threads (logical cpus).
I've updated the graphs shown here http://goo.gl/1MLFf, see the "SLOB - cores vs threads" section
