Slow File Transfer Speed

[uncleiven]

I have a 2012 Mac Mini which I use as my media server, but I also have CouchPotato installed so I can let that run in the background doing what it needs to do.

As part of the progress, CP is setup to move the complete file (once downloaded) to my NAS (Neater MyBook Live 2TB), which is connected to the same LAN (both Mac Mini and MBL are connected via Gig Ethernet).

When I first started to use the Mac Mini, I was using the original 500GB HDD and when I observed the file being moved by CP (using iStat Menu), I could see the transfer speeds were only around 2-3MBps and it would take ages to move it across, this speed is in fact slower than the actual download speed.

I also have a Late 2013, MBP Retina and using the same program and process, a file would transfer at around 40-50MBps (this is over a WiFi connection), to the same router and NAS.

I was planning to upgrade the Mac Mini to a SSD, which I have now done, but yet the same slow speeds remain.

I am not sure what can be causing this as I thought it might have been down to the original HDD in the Mini.

I know the other hardware is capable as I have seen much greater speeds as mentioned above on my MBP.

Any ideas as to what could be causing this?

Thanks

Could be your switch or router? Try a normal file to see how long it transfers? Does Couchpotato have a bandwith upload/download cap in the settings?

I only have a router, no switch.

There are no settings like that within CP.

As a test, I've transferred a large file over to the NAS from within finder and that hit 40+MBps.

As another test, I've mounted the NAS folder using AFP rather than SMB so I'll see if that changes anything.

It is a little difficult to figure out from your comments what "this" is.

I gather you have an external disk connected to a router (Apple airport?) and neither the router nor the disk nor their connection (ethernet?) has changed. The mini is connected to the router (ethernet?). The mac book pros is connected to the router (bluetooth?).

The mini gets about 2-3 MBs while the mac book gets about 40-50 MBs. You thought by switching your mac mini from HDD to SSD the transfer rates would go up to the speed of the mac book, but they did not.

Clearly there is some problem with the ethernet connection to the router.

Success... It seems to be working now I've mounted the NAS folder via AFP.

Currently getting 46MBps

The Op's "this" referred to the slow transfer speed of the mini before and after the SSD upgrade. The "disk" was a NAS (Neater MyBook Live 2TB) and both the NAS and mini were connected by Gb Ethernet LAN cables. The 2013 MBP beat the mini's transfer rate over WiFi while otherwise using the same software and connections.

should SMB slow it down that much though? that seems kind of odd to me too...

"Too"? Did someone else express doubt about the AFP versus SMB speed question? There is a history of connection and transfer speed differences. Sometimes the speed differences are large.

Well changing to AFP certainly made my file transfer a lot faster, so for me, there was certainly a difference between the two protocols.

Yep, I learn a lot from these forums.
