Slow unpacking after upgrading to OS X 10.9

Post by jojowasher »

I upgraded to OS X 10.9 a couple days ago, and ever since the unpacking phase in sabnzbd is taking forever! I downloaded a 3GB file, and it took 3 hours to unpack... just a small 400mb file takes about 5 minutes, used to take 10 seconds.

I have reinstalled sabnzbd, that didn't help.

When I look at my system info the CPU, memory and hard drive are all barely working, and I am downloading and extracting to the local computer, a nice fast SSD.

Any ideas?

Thanks,
Jojo

Unpacking is done by unrar.
We'll soon add the latest release to SABnzbd.
Maybe that will help.

When it's ready. Disappointing answer I know.
Testing this kind of stuff is just time consuming.
And then there's Windows 8.1 also :(

I haven't had problems extracting locally like the OP; it's across the network I've had problems with 10.9 - files download locally to Mac then extract Mac -> Time Capsule router/switch -> DNS-325 NAS and take 10x as long as they should.

It's a problem with unrar rather than sabnzbd itself, and using the latest version of unrar doesn't help either. A workaround is to extract files locally and then copy them to their destination on the network - shypike mentioned in another thread possibly adding this as a config switch - but I suppose it could also be done by a post-processing script.

Not sure, because my destination network for the download is not locally but stright away on the NAS where they should be extracted...
Or maybe i don't understand it right? Is the problem more when the unpacking is done over network or locally?

Did anyone also notice that the download itself takes longer? As long as i don't do anything else on my mac it downloads full speed, but as soon as something else is going on i notice extreme download speed drop downs at a point where it doesn't download at all until i stop what i was doing....
Anyone too?

Not on my system.
I upgraded my old 2010 miniMac and (while overall a bit slower) it doesn't show
the behaviour that you mention.
I'm always using a wired connection, WiFi is not recommended for Usenet downloading.

so my mac mini and NAS are wired via 1gb switch. Before I upgraded to osx 10.9 I had the same sabnzbd settings as now, which are as follows -
- incomplete folder on my NAS
- Complete folder on my NAS
When unpacking it was lightning fast, same speed as if unpacking to my local disk.

Now after upgrading to osx 10.9 I have noticed it is extremely slow when unpacking my files... for a 2GB file it took around 38 minutes.

I did a test and changed the folders to local disk, for both the 'incomplete and complete' folder and again it was lightning fast.

Nothing has changed - except upgrading my mac mini to osx 10.9, so I am assuming this is the issue...

FYI - Nas is - Synology 1813+

Cheers,
Milan

I have the same NAS configuration (incomplete&complete on NAS)! Will try to change it this WE just to see if it gets fast again...
P.S: is there a switch so that the finished, unrared file is automatically copied to NAS??

Download speed speaking I want to clarify that the speed is still the same when I don't use the computer for other stuff than sabnzb...as soon as i do other stuff on it, the speed drops fast...
Thanks

Fwiw, I have "incomplete" locally and "complete" on NAS for most of my categories, which avoids disk thrashing. It only runs into problems when an archive needs repair, par2 repair being very I/O heavy! Ideally I could use separate download, repair and extraction locations.

For this 10.9 unrar problem I don't think it matters - it's the writing to a remote drive that's slow for unrar, irrespective of where the archive is being read from.

I think for now I will just have everything local and copy it to my NAS as required.

osx 10.9 sucks IMO... everything seems worse for me

Recent hardware?
So far, I've only upgraded my old miniMac, but SABnzbd doesn't seem
to be noticabally slower.
I'll continue testing.

I have a late 2012 macmini, so it should be "Newer" than yours;-)!
Where do you extract your files? Locally or NAS?
