I downloaded DC++ today to poke around in it in preparation for the next respawn and holy shit hashing takes a long time. So this post is a warning, do not leave hashing until the last minute! I'll be sharing roughly 1.1 terabytes of 'legit backups' and it's predicting hashing with be done in...75 hours!
Hashing all depends on the speed of your computer. for instance my 1.4tb took about 2 hours, Please use .674 - it hashes, .;750 doesnt and therefore it cant be taken from multiple computers. with hashed files, if someone else has the same file and they are both hashed, dc will download it from both places and give you a faster speed.
