Force Recheck one by one possible ?
« on: July 24, 2018, 06:28:06 PM »
I'm in the middle of moving my files from utorrent to Qbittorrent,
But i'm looking for a way to (hash check) Force Recheck one by one,
when doing a force check on the files i moved it does all the torrents at the same time.

I noticed that too after I first migrated from uTorrent to qBittorrent.  However, after pausing all the files being checked then resuming, they were being processed 1 at a time.

NO .. this isnt what happens ..

I paused  .. resume -> again ALL files at the same time ..with very slooooow progress cause the harddisk nearly stalls
I paused .. issue -> force recheck.. and again ALL files at the same time ...

seriously .. IS there the option to do it torrent by torrent ?

Because there's hardly any support here,
or they don't see the issue in it.
(Noticed this also with other support questions i've asked, a lot of people have read it but 0 response)

I decided to add them paused and do a recheck 1 by 1,
i know it's a painful and long taking job.

I don't see the problem?
Probably because I misunderstood OP, but for me, if I need to check 30 torrents, I select them all, and they will slowly get checked.
Not sure what OP aims for...

If you wanted to check one by one (for whatever weird reason), you could cook up an AutoHotkey script that would go one-by-one. Again, it does this automatically, so? I don't know?

If you don't have a powerful machine or running it in a vmware checking all the torrents at the same time is to much stress/strain on the server or harddrive what eventually results in a slower process before it's finished.
If it would be checked 1 by 1 it would have a less strain on the system and your hard drive.
And would eventually be faster and your system would be still useable.

ALL torrent clients I have met so far do a force-recheck file by file .. .. only qbittorrent tries to do it on all torrents at the same time .. this causes a lot of unnecessary head movements for physical hdds - AND SSSSSLLLLLLOOOOOOOWWWWWWS the whole process down - you write it yourself  .. so unless you use a SSD - which is not a good device for torrents from my experience (you eat the possible writes way too fast) ..
so until qbittorrent learns to do it .. its painstaking method by hand



thx Ironman

There's a couple qBT github issues on this subject:
[Behavior] Force Recheck of Multiple Torrents
https://github.com/qbittorrent/qBittorrent/issues/9120
Current Behavior: Performing a Force Recheck on multiple selected torrents results in concurrent scans of multiple files across multiple torrents all at the same time. On platter drives, this means lots of random seeking (slow).

Desired Behavior: Sequential file reading by queuing rechecks one-at-a-time per storage device.

and:
qbt with lt 1.1 has worse torrent rechecking/creating speed on Windows
https://github.com/qbittorrent/qBittorrent/issues/9061

...and probably others I missed.

The problem may have already be fixed in a later version of libtorrent...
