So when I'm doing a reindex on x64 workstation 32gb ddr3 ram, 2tb sata ssd, i7 3.5ghz and dbcache=12000.      I don't seem to really see any resource maxed out and I'm trying to figure out the bottleneck... I think this is during the block indexing before the signature verification.   Could the ram IOPS be the bottleneck?
