Vyos low performance with Dell R610

General questions
1

Hi,

Recently I had installed an server Dell R610 with 2 Ethernet cards SFP+ 10Gb.
I installed the VyOS 1.3-rolling-202006090117, and I need config 6 sessions BGP. I up the first session with 300~400 Mbps and run ok, but when I up others sessions and the traffic up to more than 1 Gbps than the traffic go down to 750Mbps and don’t up.
The vyos is connect in a switch Huawei S6720. I yet change the cards and nothing…
I have another VyOS in a Dell R210 and work fine, with the same interfaces.
Detail, if I apply any changes, when the commit command is running, traffic will increase to normal and after this reduce again to 750Mbps …

Can I make anything to resolve this problem?

I need a help

Thanks,

Sidnei

Hi @sidnei, I don’t see any issues with IRQs. Did you take this screenshot when the issue appears?
Can you check crc and other errors on interfaces?
sudo ethtool -S eth0

Hi, The cpu and irqs is very low ever…

sudo ethtool -S eth4

Hi @sidnei, it looks ok, but I think you can also fix rx_missed_errors by increasing NIC ring buffers. And enable ntuple for better balance offloading.
As for the issue, this is very odd. I don’t see any reason why traffic goes down without any CPU loads.
