Optimal tune for 8 cores After deep tests Louis Zulli found on his OCTAL machine that best setup for an 8 core CPU is as following "Threads" = 8 "Minimum Split Depth" = 6 or 7 (mSD) "Maximum Number of Threads per Split Point" = not important (MNTpSP) Here are testing results: mSD7 (8 threads) vs mSD4 (8 threads): 291 - 120 - 589 mSD6 vs mSD7: 168 - 188 - 644 mSD6-MNTpSP5 vs mSD6-MNTpSP6: 172 - 172 - 656 SF-7threads vs SF-8threads: 179 - 204 - 617 Signed-off-by: Marco Costalba <mcostalba@gmail.com>
