This is the lowest end specification run I've ever attempted.
8 dual cores (16 logical) @ base clock 2.1GHz
8 GiB 2400Mhz RAM
2TB 560/530 MBps SATA SSD
7 year old Dell board
2.3Gbps peak measured WAN bandwidth.
It completed a full chain sync to block 840,000 in 2:15.
I just cranked up the thread count from 16 to 32, after trying several different levels. I was running 16, which was optimal for my 1Gbps network. But 32 is optimal now, and it's running maybe 10% faster. 45-50 minutes?
