I am downloading a very large torrent (~60GB) and when deluge clients starts up it takes a lot of time to check the parts downloaded during witch it uses a lot the hardisk that leads to a very slow computer.
Is there a way to skip this checking ? or make it be less aggressive on the hardrive ?
Try to pause the download in Deluge before stopping it - this way, I believe, it will not verify the local data when you start it
The checking is part of the way Bittorrent works. Since the BT protocol treats each chunk separately, the client needs to make sure that every chunk has the proper checksum/hash before it "knows" whether a chunk has been downloaded or not.
Usually it happens pretty seamlessly in the background, but for a 60GB download, the program will have to check every bit of the 60GB set aside on the hard drive to see what's been downloaded and what hasn't been. I don't think there are clients that don't do this check when starting a new session, since I imagine it'd still have to check to make sure nothing's been moved/changed/deleted since the last session
To Shane "I don't think there are clients that don't do this check when starting a new session". Yes, there is: uTorrent. It saves the session, so after a reboot it doesn't have to recheck everything. Having open 400GB of torrents, this is a lifesaver-feature. The main reason why Deluge isn't a good torrentprogram yet.
~/.config/deluge/state directory. See some data it saves: dev.deluge-torrent.org/ticket/367#comment:6
It's not possible to skip this check in torrent clients.
