Synology NAS via Ethernet - more fun n' games

 Following on from an earlier ( wow, two years ago ) post: -

Synology DS414 - From Megabits to Gigabits

I was talking with a colleague about the speed of the Ethernet between my Mac ( now a more modern 2018 MacBook Pro ) and my DS414.

I wanted to test, and demonstrate, the speed of the 1 GB/s Ethernet connection between the two devices: -

MacBook Pro


Synology DS414


Or, via the CLI: -

MacBook Pro

ifconfig en8

en8: flags=8963<UP,BROADCAST,SMART,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu 1500
options=6467<RXCSUM,TXCSUM,VLAN_MTU,TSO4,TSO6,CHANNEL_IO,PARTIAL_CSUM,ZEROINVERT_CSUM>
ether 00:e0:4c:68:03:70 
inet6 fe80::14a7:3984:6d54:14f3%en8 prefixlen 64 secured scopeid 0xb 
inet 192.168.1.21 netmask 0xffffff00 broadcast 192.168.1.255
nd6 options=201<PERFORMNUD,DAD>

Synology DS414

ifconfig eth0

eth0      Link encap:Ethernet  HWaddr 00:11:32:25:58:91  
          inet addr:192.168.1.100  Bcast:192.168.1.255  Mask:255.255.255.0
          inet6 addr: fe80::211:32ff:fe25:5891/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:90968788 errors:0 dropped:0 overruns:0 frame:0
          TX packets:13099066 errors:0 dropped:19 overruns:0 carrier:0
          collisions:0 txqueuelen:532 
          RX bytes:2857752864 (2.6 GiB)  TX bytes:36719514 (35.0 MiB)
          Interrupt:8 


but, to "prove" the performance between the two, this is what I did: -

Create a 10 MB file

time dd if=/dev/zero of=tstfile bs=1024 count=1024000

1024000+0 records in
1024000+0 records out
1048576000 bytes transferred in 4.880373 secs (214855709 bytes/sec)

real 0m4.886s
user 0m0.470s
sys 0m4.381s

Validate the file

ls -alh tstfile 

-rw-r--r--  1 hayd  staff   1.0G 21 Nov 13:38 tstfile

Upload the file to the NAS

scp -P 8822 -c aes256-cbc tstfile admin@diskstation:~

tstfile                                                                                                                                                                                              100% 1000MB  22.9MB/s   00:43

which, in part, shows an upload speed of 23.0 MB/s - which ain't too shabby
