1) If I choose P-1 work should I run on 8 threads or 4?
(2560K of 4096K reserved 24/7, i7-2600k on 64bitWin8)

2) If 8 threads is faster is that enough memory? Candidates are at 62-63M.

Thanks.

My evaluation of 8 threads on P-1 testing showed the same linear degradation in throughput as seen on LL tests. You are just weighing time vs concurrency. Personally I only run 4 threads on my i7 cuz it kills me to see my i5 based PCs kicking butt on my i7. An i7 with hyper-threading off is basically an i5 with more L1/L2 cache.
