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

          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

Yay, VMware Fusion and macOS Big Sur - no longer "NAT good friends" - forgive the double negative and the terrible pun ...

After macOS 11 Big Sur was released in 2020, VMware updated their Fusion product to v12 and, sadly, managed to break Network Address Trans...
