2 days ) then is not a bootstrap in the real meaning, at least what I expected.
I used snapshots in the past and it will take only the time to copy the files in the NOBT folder.
If you have the wallet synced, please upload somewhere the 3 files needed for the snapshot ('database' folder, 'txleveldb' folder and 'blk0001.dat' file, then I and other users can replace the files in the wallet folder and the sync will start from there. It will take less time than bootstraping with your method.
