Synology NAS slow to update thumbs in manager

Post by Fladmas » Sun Sep 16, 2018 3:17 pm

Hi,
I have my images stored on a Synology DS218+ with 200 to 700 images per folder. When selecting a folder in the left pane it takes around 12 seconds to show the thumbs in the right view/manager-pane. I can sit and wait until it updates the images one by one.

It seems as if it is creating the thumbs every time? Is there maybe a setting I have missed or set wrongly?

Best regards - help is appreciated!
Andrew

Hi,

do you use GraphicConverter 10.6.3? That does normally cache the thumbs.
Do you access the NAS with afp or smb?

Hi Thorsten,
thank you for your help!

I have now tried both AFP and SMB and see somewhat similar speeds. I am running latest GC 10.6.3 (3158) on a 2010 Unibody Macbook Pro running ElCapitan.

On a Synology 1515 under OS 6.2 with a 1000 Mbps networks the display is quasi instantaneous on a MBP 2011 under macOS 10.13.
What is your network speed ?

I had similar issues with working directly on a NAS and switched back to local disks instead of network drives.
I also experienced file locking issues on the Synology NAS.

You can optimize the general access by disabling the following options in GraphicConverter :
  • Uncheck the option „Create custom enclosing folder icon“ in the preferences Browser/General.
    Uncheck the option „Support Spotlight Comment“ in the preferences General/Misc.
    Uncheck the option „Automatic Volume Discovery“ in the preferences Browser/Display.
    Turn checking folders for subfolders OFF (this made a huge difference)
Finally, in general, Mac's are slow with SMB out of the box. You can reduce security overhead by following article : https://support.apple.com/pl-pl/HT205926. This has nothing to do with GC but is a macOS specific issue. My write to NAS speed went from 30 MB/s to 58 MB/s.
