SABnzbd Forums

Hi,

I've read all the documentation online. I've looked through all of the sabnzbd+ menu options. I've been using sabnzbd+ for years. I've never been able to figure out how to restrict downloads to "one at a time" -- serially.... no simultaneous downloads.

Is this possible?

thanks,
sam

I don't understand your question; I would say SABnzbd does only one download at a time?

If you mean no downloading during post-processing, check the option "Pause Downloading During Post-Processing"
If you want only one download thread, set the connection number of your download server to 1

HTH

There can be some overlap between jobs.
There's an option in Config->Switches that minimizes most of the overlap (Only fetch from top of queue).
And of course what Sander said.

Well, not in my experience.

No, that's not what I mean.

Thanks, I'll try that. I have it set to 8 now in order to maximize throughput. I thought even if I changed it to 1, then sabnzbd would multiplex all the nzb download tasks over a single connection. That's how a lot of other software works. Maybe not sabnzbd+. I'll try it.

Thanks!!

Results:

When I change the number of connections from 8 to 1, my throughput is reduced from 1.5 MB/sec to about 950 KB/sec.

In regards to number of simultaneous downloads:

1. Add nzb to queue. It starts downloading.
2. Add another nzb to the queue. It's not downloading (I'm checking this by looking in my "incomplete" folder--i.e., downloads which haven't completed). There is no entry for it in the "incomplete" folder. However, the GUI show a "pause" button. Why? That is very confusing. See screenshot.

Don't drop down to 1 thread. Thread count has nothing to do with what you're seeing.

SABnzbd downloads via a Queue, and downloads only one thing at a time. Per-item pausing in SABnzbd lets you maintain your queue order but pause individual items. For users with very large queues this can be more useful than changing something's priority or manually re-ordering the list. We have to show a pause button per-job because SABnzbd has the ability to send jobs to the queue that start off paused (useful for RSS feeds that might not always have things you want).

SABnzbd already does exactly what you want, stop worrying about it.

I understand.

My point is that the per-item pause button should initially display the "play" icon, not the pause icon.

This is a debate we've had several times in the past. Should a button show the function's status or the function's action? In this case we chose the action, not the status.

Is there a way I can actually get SABnzbd to download more than one NZB at a time? I can't seem to find the option in any of the menus that I have looked through.. I would like to have multiple threads going to maximise the download capability of my internet connection.

Thanks

SABnzbd already utilizes all connections with one NZB at the time.
