Hi all,
I have installed OPNsense version 16.7 on a KVM virtual environment.
When performing tests using iperf3, I noticed that the application is only using 2 vcpu cores out of 4 - which is the total number of cores allocated to the VM.
On the web-interface I can see that the CPU load peaks at 50% - even if I increase the load.
Could you please guide me to resolve this issue please?
--Screenshot attached.
CPU 0 0% idle
CPU 1 0% idle
CPU 2 99.6% idle
CPU 3 100% idle
Thank you in advance,
regards,
Malcolm.

Hi Franco,
Thanks for your reply.
Since I'm using a virtual environment, I am not really sure what is being used. I am also new to FreeBSD - yet I've been using CentOS for quite some time now.
Is there an better NIC driver which I can use?
Thank you.
Malcolm.

Hi,
I have checked further and found out that the cloud environment is using KVM with Virtio NIC driver.
Any ideas please?
Thank you,
Malcolm.

Hi Malcolm,
Can you somehow switch to Intel e1000 emulation? That should help.
Cheers,
