I have a Mac Mini that is solely used for sabnzbd and it is routinely bogged down by unpacking downloads.
Does anyone have any tips to improve unpack performance on this hardware or is it time to replace the mini?

sabnzbd v1.0.3

Here's the performance test results

Here's an example download

One ore two years agao, MacOS (then: OS X) had a problem with unpacking to NAS (and external) drives. But "/Users/x/Downloads/" is a plain drive inside your Mac, isn't it?

The complete folder is a local drive. However, I think it is overwritten by the category's final destination which is a mounted NFS drive.

Switching over the complete and incomplete folders so I can test their speed:

Code: Select all

System Performance (Pystone)77023  
Download folder speed105.7 MB/s  (/Volumes/Public/sabnzbd/…)
Complete folder speed100.0 MB/s  (/Volumes/Public/sabnzbd/…)
Used cache0 B (0 articles)

Looks about the same. And it was copying to the destination folder quickly. Just a problem with unpack. Is there maybe an update to the underlying unpack libarary I can do that will improve performance when unpacking on NFS clients?

category's final destination which is a mounted NFS drive.

I think the unpack is done towards the Complete folder, not the category directory, but I could you nonetheless test a full download with the Temp, Complete and Final destination set to a plain, local drive. No external drive, no mounted network share.
