Hi Team!
The first test of Datacoin v0.16.3.0-74075b1f3-dirty Windows is complete.
The sync took 9 hours from beginning to end on a duocore Intell XeonR CPU E5-2673 v4 @ 2.3GHz with 4 GB RAM.
That's inline with 15.9, and perhaps even a bit better

The start was shaky, header sync stalled 4 times and I had to restart the instance.
Log below:
6:40 found 2 nodes within a minute in all cases
6:45 syncing headers to 22.6% quickly, stopped (no spike in cpu or ram, connections were there)
7:04 restarted dc and it went to 22.9 but immediately stopped syncing headers
7:10 restarted, went to 23.1 and stopped syncing headers
7:14 restarted
went solid to 87% header sync then cpu spiked and it powered through to 100 sync all headers at 7:48
7:48 all headers synced -- block now syncing with network, wallet estimates 15 hrs.
still synced to 2 peers.
8/9/20
12:19am
now has 4 peers
2:48
90% progress
3:45 fully synced at 1.8 gig ram.
shut down wallet and restarted (per best practice after a full sync).
ram now at 1.2 ram
IP of the test wallet is 40.87.106.229
Tests will continue!
Great work Hamburger -- let me know how I can be of continued help

Kind Regards,
DataSea
