Thank you very much

. How long does it take to reindex it? A window is opened more than one day and is constantly changing.

On Windows it can take days

, blockchain is around 14GB atm, Linux is little faster.
Complete re-sync is maybe 10-20% slower than reindex. Not a big difference.
And one more question. How do I know that the reindexing process has finished?
