VM Windows Server 2019, slow network speed

[Silcati]

Hello, I have 8 x 1Gb NIC, bond mode balance-rr, VM Windows Server 2019. But the maximum network speed is 246 Mbits on the VM. The VM network uses the vmbr0 bridge.

What is the correct configuration so that the network speed is around 1Gb?








Thanks for the help

Thanks,

Thanks bro, the speed was solved with balance-alb, but now you cannot enter shared folders on some servers but on other servers it is possible, the error is 0x80070035, I found several possible solutions that I found but I can't solve it. With the balance-rr configuration, it is possible to ping or enter servers where they cannot be seen on the network.

I don't know if bond mode balance-alb is recommended for the bridge for VMs, I use it mainly as failover and one host with only 2 NICs in the bond.
I also keep bond for one NIC config because i use post-up command in vmbr0 to join any "en" devices into the bond, to not loose network if hw changes...

Please help me with examples of the post-up command, thanks

post-up command doesn't change anything, it was just my case for a sort of fail over.
try to use 2 vNICs in your VM, instead 8, if the problem goes.
