Connect your MyCloud device directly to your MacBook via Ethernet, with no router or other device in between. Under the Sharing
System Preference Pane, enable Internet Sharing
. In the "Share your connection from" pull-down, select Wi-Fi
. In the box below 'To Computers using', check Ethernet
. This will give your MyCloud
a DHCP address to work with your Ethernet interface.
You should now be able to connect to your MyCloud
in the usual way.
Begin a large file transfer as a test.
Open Terminal.app
, in /Applications/Utilities/
.
To see with what link speed your MyCloud
has connected to your Macbook, do:
ifconfig en0
or perhaps ifconfig en2
if using Thunderbolt. This will give an interface description like:
[Nevins-Mac-mini:~] nevin% ifconfig en0
en0: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500
options=10b<RXCSUM,TXCSUM,VLAN_HWTAGGING,AV>
ether 3c:07:54:5c:ab:ad
inet6 fe80::3e07:54ff:fe5c:abad%en0 prefixlen 64 scopeid 0x4
inet 192.168.2.122 netmask 0xffffff00 broadcast 192.168.2.255
nd6 options=1<PERFORMNUD>
media: autoselect (1000baseT <full-duplex,flow-control>)
status: active
[Nevins-Mac-mini:~] nevin%
The status: active
line means I'm looking at a connected interface, and the media:
line above it means I've got a Gigabit connection that's full-duplex and supports flow-control.
With a large file-transfer in progress, look at traffic statistics with netstat
:
[Nevins-Mac-mini:~] nevin% netstat -vI en0 8
input (en0) output
packets errs bytes packets errs bytes colls
03:36:07 3174 0 305928 6083 0 9171948 0
03:36:15 3085 0 297366 6145 0 9268910 0
03:36:23 3166 0 305142 6071 0 9155228 0
(The trailing 8 tells netstat
to take 8 second samples, which means the 'bytes' column is actually a bits/sec average)
This shows I was sending data at 9 Mb/sec, which is about right for my network connection, with no link-level errors.
I don't know what the max throughput should be for your equipment, but even if you were only getting 10% of a Gigabit/sec, 125 Gigabytes = 1000 Gigabits. At just 0.1 Gb/s, that would be 10,000 seconds, or just under 3 hours.
Are your cables home-made, by chance?
Thank you @Nevin Williams, That was such great detail. I believe I know what happened. With a large file transfer with around 10,000 folders it takes a long time to set up all the folders. For the first hour the transfer was going super slow then after that it was able to transfer it over in about 4 hours. I don't know why it takes so long to transfer iPhoto library even with all the folders (still just bits). There are formatting issues I have to take care of now. I did use some of my home cables but i also tried manufacture ones. – Saduser – 2014-06-01T23:48:28.433
