FWIW, a couple years old i7 w/SSD, 8GB RAM and 100Mbps connection, took me a few minutes shy of 2 hours to sync from scratch last night. I deleted my older appdata folder & skipped the db conversion as that felt like it would wear the SSD at lot more than a plain re-sync.
As always, great work from everyone that contributed to this release.
Thank you guys for what you all do for Monero and this community.
Happy forking gents!

It took 2 days for me.
2 days of continuous thrashing of the HDD.
Obviously we need an SSD...
That was a problem for my old machine with cheap HDD and 4GB RAM. Not enough memory makes the HDD work harder. Maybe it fried mine?
New machine = still HDD but better and 8GB RAM. Estimated snyc time was <12 hrs.
