strange network issue

[phier]

hi,
i am running freenas 9. I installed two ubuntu's 18.04. each into separate vm. I found out very strange issue regarding network performance. My provider is 150/10mbits.

If i run speedtest on roon-server its still 150/3 whereas on ubuntu-server-universe still 150/10

Inside vm roon-server there is eth0 interface, and inside ubuntu-server-universe the main network interface is called enp0s3.

I have no clue ... what kind of issue is that... can i somehow also remove "net igb0" option from roon-server?


Thank you!
