I haven't seen what you're looking for out in the wild.
~if let the core syncs by itself. Perhaps will take days, even 1-2 weeks. I know there is a website offer the torrent, but the download speed is not that quick, 300 kb/s to 1+ mb/s.
The download speed depends on your hardware speed. From what I've read, I think syncing on Linux is much faster than on Windows, probably because of better (cache) memory management. My 3 year old i3 can download the full blockchain in a day, if I prune to a RAM drive, with default dbcache settings
For a fast download you'll need:
-enough RAM for file caching
-an SSD
-a fast CPU to verify blocks
-(obviously also fast internet)
If you run an hdd on Windows low on RAM it will indeed take a long time to sync.
