Title: [SOLVED] KVM "poor" performance ?
Post by: lebertu on December 10, 2017, 01:04:38 pm

Hello,

I've decided to go OpnSense for my router appliance, I've decided to run it on my old media server that I've converted to a virtualization server on debian (mini-itx, i5-3470s, 8G RAM, intel 350 t2).

I've allocated 2vcpu and 3G to OpnSense and the 2 nic are running on passthrough mode (virtio), i was not able to make VFIO work because of iommu grouping ...

When connecting the media converter directly to my laptop I'm getting 930Mb/s but when connecting it to my box I'm getting 480 Mb/s.

I'm new to OpnSense so I'm currently running the default configuration but I'm not sure what is the bottleneck :

- OpnSense ? filtering ?
- Virtualization ?
- Hardware issue ? "fake" intel nic ?

Try e1000 instead of virtio
