Slow unpacking after upgrading to OS X 10.9

[Strakekine]

Hi
I send them a message in theit forum. Let's see.
But i tried using sabnzb without sickbeard. (Manual download of nzb and put it in watched folder)!
Download pretty fast but here post processing (unpack&copy to completed folder on NAS) lastet 58minutes for 780MB...
So it is also slow.
So i am pretty sure it is the connection (copy files) from maverick to my NAS who is the problem. And that is why before the download to my NAS was so slow also... There is a problem wit sabnzb sharing or sensing files with my NAS...

It's the combination Mavericks, unrar and NAS.
SABnzbd itself has no influence over this.

[Strakekine]

So problem isn't sabnzb nor sickbeard?
It comes from all the mavericks sharing bugs?? And what is with unrar? Is it uncompatible with mavericks?
My NAS worket with 10.8, so the thing which changed is mavericks. So for me thats the problem. Had also a problem with xbmc stuttering. Changed some config so that mavericks just uses smb1 and xbmc is running again. But copiing files is still slow. But found a lot about this on the net the last few days...
Need to wait then, but thanks guys for your help

unrar already has a pretty bad performance when unpacking to a networked drive on any OS.
On Mavericks it's worse for some reason.

[Strakekine]

Yeah, but this isn't a unrar problem, cause he extract the file correctly on my local HDD. It is the copiing process from HDD to NAS which takes forever...
So I cannot blame unrar for this;-)

[shypike]

Weird.
This weekend I'll have a closer look at Mavericks.

[Strakekine]

Thanks

Did you have time to check on mavericks?

[shypike]

No, the todo list is just too big.
Preparing release 0.7.17 this week.

Same problem here.

After upgrading to Mavericks i am getting slow performance when unpacking to NAS.
Everything was fine before update.

When trying to unpack locally everything is fine.

[Strakekine]

ok. cool. going to wait for the update then.
but if you haven't gone through with your todo list, will there be some changes concerning this problem in the update???

Probably not, but the test was more to see the issue for myself.
I expect that SABnzbd itself is not a factor in the problem.
I might be able to do some tweaking of the unrar parameters.
More likely that unrar and Mavericks don't go together very well (at least in combination with a NAS).
Some testers have looked at unrar 5, but so far it seems very buggy.

Probably not, but the test was more to see the issue for myself.

so you were able to see the issue by yourself? at least you would believe us then:-P

I have not fully followed this thread, and I have no OSX, but: Would this analysis help:

Make sure you have a full set of rar files on your Mavericks system. Go into that directory and issue the unrar command to unrar unto your NAS drive (see below). Measure the time ... fast or slow?

If it's slow, it's the proof that the problem is in the Mavericks-unrar-NAS combo. Not in SABnzbd.
Workaround is then: let SAB unpack unto your local drive, and then do a plain mv / cp to your NAS (possibly using a post-processing script)

FWIW: This is the unrar command that SABnzbd uses

Code: Select all

Running unrar ['/usr/bin/unrar', 'x', '-idp', '-o-', '-or', '-p-', '/home/sander/Downloads/incomplete/DAT/Hans.part01.rar', '/home/sander/Downloads/complete/_UNPACK_DAT/']

... so use such a unrar command: check your own sabnzbd.log. Replace the last parameter with the NAS path.

EDIT:

PS: If you want to create a set of rar files form a certain file "some-big-file.iso":

Code: Select all

rar a my-rar-files -v10m -m0 some-big-file.iso

which will result in:

Code: Select all

-rw-rw-r--  1 sander sander  10485760 dec  3 18:27 my-rar-files.part01.rar
-rw-rw-r--  1 sander sander  10485760 dec  3 18:27 my-rar-files.part02.rar
-rw-rw-r--  1 sander sander  10485760 dec  3 18:27 my-rar-files.part03.rar
-rw-rw-r--  1 sander sander  10485760 dec  3 18:27 my-rar-files.part04.rar
-rw-rw-r--  1 sander sander  10485760 dec  3 18:27 my-rar-files.part05.rar
-rw-rw-r--  1 sander sander  10485760 dec  3 18:27 my-rar-files.part06.rar
...

which you then can unrar unto your NAS drive.

[Strakekine]

Ok sorry, you got it partially wrong.
It is not only du to rar, because i let it extract locally (so the mkv file is on my local drive) and the sickbeard script which copies the file to the NAS needs forever.
So it is just the normal process of copiing a file which needs a long time. If i take the same file and copy it manually then it goes fast as ever?!
