Hello, I am a newbie in proxmox, and having problem about slow speed on second bridge on OpenWrt SNAPSHOT, here is my NETWORK interfaces :Network.png

Here is how it's configured in OpenWrt VM :

As you can there are 3 bridges assigned to the VM, for lan1 I am getting maximum full speed while for lan2 I am getting only around 10-12 Mbps.

In lan2 there is a gigabit switch in which there are various devices connected to it, for example a wifi router, which I run speedtest.net.

It's a self-compiled OpenWrt SNAPSHOT flavour, while running it on baremetal doesn't have these problems.
 
It seems that settings MTU into 1500 for all bridges is make it working, does it the correct approach?
