default cache, with '-par 8', initially it seemed to run in single thread mode - first 193 000 blocks loaded significantly slower than on Ubuntu (same hardware), reason perhaps is slower storage.
After block 193000 the average CPU utilization rose to ~75%. Looking at threads, there were 16 threads executing same code of which 8 were actually active.
92 minutes real time, 6h:05m CPU time, 72% average CPU utilization, 235 MB peak memory working set
I then tried with '-par=4' and setting CPU affinity to physical cores only. Now there were initially 12 threads at transaction crunching, with again only one actively processing pre-SatoshiDice blocks.
