Q: Performance after update to Maverick a total disaster.

Could be Spotlight indexing.

I have exactly the same issue and have logged a call with Synology who claim there is a fix for it.

I have a DS212 running 4.3-3810 using Mavericks on my new MBP which is now unusable when trying to sync with my iPhone over wifi. The NAS starts slowly transferring then reaches 10-15Mb fine for about 10 secs then drops to a few 100k for a period before speeding up again. It never stays at a constant speed like it used to meaning my sync takes hours and hours now. Even syncing large files the transfer is up and down instead of a constant speed. I have also noticed the disk lights are flashing even when I am not doing anything but they start as soon as it gets mounted on the Mac.

Someone on the forum told me there was a fix

"Synology Hi Paul, I think there is now an update to use with Mavericks, please contact our support team for the information"

As soon as I hear back (assuming I do!) I will let you know.

Same problem with two iMacs and Synology Ds1512+, DSM 4.3-3810.

Switched on and then off afp, smb2, restarted, nothing to do. Unusable.

Any news?

Thanks,

Max

Some discussion here: http://forum.synology.com/enu/viewtopic.php?f=64&t=75221&start=30

You updated *both* Macs to 10.9?  I went with one, tested a while, then did the other. But not using your NAS.

No help at all from the useless people at Synology who couldn't even seem to grasp the basic problem.

It now take so long to sync with my iphone that I have decided to go back to using direct attached usb drive.

If the speed stayed at 5-10m/b I would be happy but when it splutters and drops to a few 100k for long periods at a time my sync is now an overnight job instead of an hour or less previously.

Synology rolled out update 1 and Mavericks jumped to 10.9.1 but neither made any difference.

I have similar issues after upgrading my iMac (late 2012) to 10.9 and my Synology DS713+ to DSM 4.3-3810.

I get performance issues when I stream movies via PS3 Mediaserver, copy large files etc. It sometimes looses connection to the Diskstation and other strange things. My system are directly connected via a gigabit copper network.

I have tried all of the above as well.

So guys do we think its a Synology or Mavericks issue?

I am happy to get another NAS but dont want to get a Synology incase its their DSM software. But if generic issue may need a fix from Apple.

Any suggestions as Apple and Synology have come up blank?

I've got this same problem using mavericks and lastest DSM on Synology 213+.

File transfer speeds are a laughable 528k a second. Used to be 85mb.

Most times the transfer just hangs and I have to use Disk Utility to kill the finder.

Very disappointing.

Well from I can see when the IO goes to over 90% the transfer drops to a few hundred k for upto 40 secs then the IO drops down to > 35% and transfer speeds increase upto 10Mb/s over wifi before slowing again after about 30 secs.

Right now my DS212 is flashing like mad but I am doing nothing at all on it so what the heck is it doing??

During a copy the lights flash like mad but you can hear the disk access and transfer speed is rubbish and then it goes quiet and transfer speed jumps. So to me its doing some kind of buffering instead of just a constant speed.

My iphone now takes 4-5 hrs to sync with my library on the DS212 due to these slow downs and speeds ups.

If I ditch Synology will I be any better with someone else?

I don't think you will, flexiboy. I am having the same problems with my QNAP TS-119 NAS>- I also run an iMac, a Mac Mini, and a MacBook Air. Only the Mac-mini has been upgraded to Mavericks, and only the Mac Mini fails on an Time Machine back up to the NAS.

Got a new MacBook Pro with Mavericks and it takes almost 2 minutes to copy a 10MB file from a Netgear NAS. This is terrible performance for something so basic. Mavericks overall does a number of things slower on what should be a much faster machine than my old.
