Slow network

[ballybob]

I have a proxmox host with two built in 10G network cards.
It is a new install so it isn't doing much, I have a Linux Ubuntu VM and a TrueNAS, netiher in production.

I started to test performance on my TrueNAS and noticed it was really slow. 29MB/s on my primary nic (1G), where as testing the storage gets 400-600MB/s depending on read/write. I added the 2nd nic to the VM that is connected to one other machine via 10G and I get the exact same speed.

I tried iperf3 and seeing the same exact speed (29MB/s) on both nics. I tried changing to E1000 and multiqueue 4 and neither has changed anything.

My linux vm is getting 110MB/s on the 1G link and about 300Mb/s on the 10G link. The 1G link is ideal the 10G is still quite a bit lower than it should be but much better than they 29Mb/s I'm getting in the TrueNas Core (Freebsd).

Update:
After rebooting, and dedicating the 2nd nic to the TrueNAS VM, both NICs are performing better. The shared nic is now seeing the same 111MB/s as the Ubuntu VM, the dedicated NIC is reaching 400-500MB/s, still almost half speed, but way better than the 29MB/s I was seeing before.

VirtIO with multique should be faster than e1000

curious if you tried truenas scale?

I have not tried scale, since I won't be doing VMs or anything but file sharing protocols, Scale would just be slower. I just posted an update, I rebooted the instance and dedicated the 2nd nic and seeing improvements, but I don't think it was related to that (maybe just the reboot) as the shared nic is seeing normal speeds now 110MB/s for 1G, but the 10G link is still running half speed but way faster than before.
