Performance Issue OPNsense 20.1.4 on Microsoft Hyper-V VM Gen1

[heuschmann]

Hello,
I run an opnsense vm under Microsoft hyper-v 2019. Among other things, the OPNsense serves as a NAT router.
Internet access from my internal network works efficiently and without problems via OPNsense.
Downloads from the Internet are also very good.
The problem I have is that when accessing remote RDS farms the network performance is very bad.
When I connect to an RDS farm from an internal client and generate this load (moving windows, scrolling within browser pages), the performance and experience decrease extremely.
Then there are also ping dropouts.
I deactivated VMQ on the virtual interfaces of the opnsense vm on the hyper-v server, but without success.
Can anyone give me advice.
Thank you very much
with best regards

Hi,
after the update to the version OPNsense 20.1.5-amd64 the problem no longer occurs.

I would still recommend switching to a Gen 2 VM. This works since at least 17.7.
