FTP transfer speed

[Matthew]

Hello,

I’ve set up a Mac Mini to operate as a file sharing server over a 10gb network. Connected to the Mac is a 4TB WD NVMe drive. Read and write speeds with Black Magic are reported as 3100MB/s. iPerf reports a consistent 9.9GB/s transfer from my Macbook to the Mac Mini.

I’m running the latest version of Mac OS and of PM.

When sending a folder of 250gb of .NEF files from my MacBook to the Mac Mini using the FTP app Transmit I get a sustained transfer rate of 1.1Gb/s which is also reflected in Activity Monitor.

When sending with PM I can get to about 300-400mb/s using 8 concurrent uploads. PM is set to send the file as is - not as JPG.

Is there any reason for the speed difference?

Thank you,

Matthew

Are you using the "FTP" uploader or the "FTP v6" uploader? If you're not yet using the FTP v6 uploader, can you try that and see if its any better?

Hello,

I was using the standard FTP uploader and getting speeds at 300Mb/s.

I've just tried FTP v6 and it's slower at around 60MB/s.

Just tested again with Transmit and getting 1.1Gb/s.

Thanks,

Matthew

I'm not sure why FTP v6 would be slower, and I'm also not sure what to else to have you try. I compared uploading with Photo Mechanic to our test server compared to uploading with Cyberduck and got roughly similar speeds. I also set up a simple FTP server on my personal laptop and uploaded to it over my home wifi network, and got similar speeds between the two pieces of software there as well, but then again, my uploads were going at about 10 MB/sec. Not even remotely close to what you were seeing, maybe I'd be seeing a bigger discrepancy if my network was capable of faster speeds overall.
