I have a Synology NAS D213+.

When I want to connect the NAS to my Mac, Finder mounts a new volume which behaves like a normal partition.

But it interacts so slowly - I click on a folder, and it takes a huge number of seconds till it's open. Explorer on Windows is much faster when it comes to network interaction.

What can I do? Change the protocol? It must be AFP, so do I have to change the protocol elsewhere in the kernel?

    I have this same NAS and have noticed FINDER is slow but using ForkLift seems much faster to browse folders and files.

    I'm using a DS411j running DSM4.1. Like you, it's noticeably slower with Mountain Lion (though it wasn't exactly blazing fast with Lion). I suspected it had to do with versions support in ML, so what I did was to run tmidiagnose and reported the results back to Apple. Commented Feb 11, 2013 at 17:09
  • You should be able to export the file system as SMB and mount it that way on the Mac. This often has better performance than with non-apple implementations of AFP Commented May 10, 2013 at 16:18

My advice would be to use NFS. You should also try to manually mount the partition from the terminal, so you can add some options too, like


This made my browsing much faster, even over wifi.
