VETH interface have such low bandwidth

Hello!
I’m considering buying a Mikrotik router. To begin with, I decided to check the RouterOS operating system in the VMware virtual machine for compliance with my needs. I realized that for my needs a docker container would be needed. My tests with different containers and different versions of OS7.x showed that the speed of the VETH interface in all the containers I tested is very low (1Mbps), although the transfer speed with the virtual router itself is 1Gbps (copying files via FTP).
Why does the VETH interface have such low bandwidth (1% CPU usage)?
Maybe I’m doing something wrong?

  1. I installed the container package.
  2. Granted container mode access.
/system/device-mode/update container=yes
  1. Confirm with a cold reboot.
  2. Reset system configuration with “Run after reset” script.
# RouterOS 7.9rc4

  1. Started the container after its extraction was completed.

Speed test from host 192.168.109.1 to VETH interface:

I also have the same problem, very low speed even though the cpu is very low, I get 5Mbps download but good upload at 950Mbps

In my case, I think this is due to the restriction in a free CHR license.

Someone could repeat my configuration on the Routeros system with a license without restrictions, and show what the result of the speed will be?
