SMBv3 is slated to be used in the upcoming release of DSM 7.0, but at this time we are unable to set this mounting protocol for Mount Remote folder to SMB3. This limitation is on DSM at it's current version. 'I have heard back from our developers and after reviewing our documentation and your current mounting method this slower transfer performance appears to be due to the fact the Mount Remote Folder options is only capable of using SMBv2 at this time. Synology support got back to me with their conclusion and closed the case. This difference persists between reboots, remounts, etc.Īny idea why this is happening? The Resource Monitor doesn't indicate anything odd except the significant CPU usage when using CIFS Remote Mount. Transfer speed varies between 48-65MB/s, not good and odd given Test 1 results. Via the Admin Mac in DSM transfer the same folders of media files from the NAS to the Target Mac. Via the Admin Mac - mount the Target Mac on the NAS in DSM as a CIFS Remote Mount. Target Mac has file sharing on with only SMB enabled. Transfer speed varies between 100-110MB/s, not bad for a Mac.Īdmin Mac is logged into DSM via Chrome and looking at File Manager. Using Finder, transfer several folders of media files from the NAS to the Target Mac. Target Mac has file sharing off, the NAS folder is mounted on the Target Mac via SMB. Target Mac - MacOS 10.14.6, transfers via SMB, SMB packet signing=off, SMB local caching=offĪdmin Mac - MacOS 10.14.6, SMB packet signing=off, SMB local caching=offĪll 1G connections for this test, the production version will be a faster NAS with 10G connections.Īdmin Mac is logged into DSM via Chrome and looking at File Manager but not doing anything. No other DSM activity going on, no remote access. all transfers from a DSM shared non-encrypted folder to a Target Mac. I set up a test scenario with an isolated network. I'm attempting to transfer files from a NAS to a Mac and the transfer speed varies almost by a factor of two depending on whether I mount the NAS on the Mac via SMB, or mount the Mac on the NAS via CIFS Remote Mount in DSM.

I'm testing a scenario to be implemented on our live show productions and have come across an oddity that I can't explain. I have filed a support request with Synology but that can take a while, perhaps someone here has an idea. I found this forum while searching and it appears nicely done.
