Default Very bad ethernet performance

Hi,

I've just got my new usb3 dock:

Code:
LAPDOCK:

  Product ID:	0x4307
  Vendor ID:	0x17e9  (DisplayLink (UK) Ltd.)
  Version:	41.89
  Serial Number:	U3D2338603657
  Speed:	Up to 5 Gb/sec
  Manufacturer:	DisplayLink
  Location ID:	0x14540000 / 12
  Current Available (mA):	900
  Current Required (mA):	504
  Extra Operating Current (mA):	0
I'm running it with latest DisplayLink driver on the following system:

Code:
System Software Overview:

  System Version:	macOS 10.13.2 (17C205)
  Kernel Version:	Darwin 17.3.0

  Model Name:	MacBook Pro
  Model Identifier:	MacBookPro11,2
  Processor Name:	Intel Core i7
  Processor Speed:	2 GHz
  Number of Processors:	1
  Total Number of Cores:	4
  L2 Cache (per Core):	256 KB
  L3 Cache:	6 MB
  Memory:	8 GB
  Boot ROM Version:	MBP112.0142.B00
  SMC Version (system):	2.18f15
In general it works fine, though ehternet speed according to speedtest.net, fast.com and iperf with a server within my local network is capped by 30.5 Mbit/sec.

It's definitely a bug somewhere in DL hardware or software because when I connect a 3rd party gigabit usb ethernet dongle to a port on my DL dock I'm getting 250Mbit on speedtest/fast.com and 400Mbit over local network.

Could you help me with that please?.. In general it's nice piece of hardware but network performance is awful.
