I all,

I have an iMac (Late-2013) connected via Ethernet (1Gbps) to a TP-Link switch (five ports, gigabit, metal case, I do not remember the model number).
Then the switch is located in a room and therefore is connected to a second switch located in "central room". This second switch is then connected, among others, to a Synology NAS.

I am transferring right now 67GBytes of data to the NAS (via FTP) and the estimated time is round about 30 mins...

How can I improve the network speed?

Thanks
Marco
 
Estimated times should be ignored. These will fluctuate depending on the size and type of files transferred.

I think you're maxed, for the hardware you have.
 
I don't know the limits of the unknown TP-Link switch you have.

What I'm suggesting is that you ignore estimated times when transferring many different types and sizes of files.
 
What is the actual transfer speed, not time. By my math, that is around 37MB/sec, which is fairly slow for a gigabit connection, but what NAS is in use? Plenty of them can't even come close to saturating a gigabit link (which is roughly 110MB/sec after overhead).

Also what kind of files. Is this 67GB of big videos? Or is this 67GBs of small JPEGs or MP3s, or even smaller files. What kind of storage is in the Mac and in the NAS?
 
The NAS is the Synology DS213j.
It is a ZIP file, 67GB big. It contains Final Cut Pro X videos.
 
With your NAS model and the file your transferring to it (writes), it seems to be running close to specs at about 38MB/s.

The advantage of the Gigabit drop is that I’m now also getting significantly better read/write speeds to the Synology (obviously). I can now read/write to the DiskStation at 85 MB/s and 45 MB/s respectively. Which is pretty great.

If I’m on my 5Ghz Wi-Fi connection I can read/write at 24 MB/s and 15MB/s respectively.


The ~7MB/s difference could be attributed to your slow notebook HDD feeding the NAS.
