Exclusive mikrotik for proxy

Hello, I have 2 mikrotiks and would like to use one exclusively for proxy and the other as router. Can anyone help me setup?

Is there a reason to do that on two devices? Why not on one?

I set up a balance and processing of my mikrotik started getting super high, so I saw what is consuming more resources from my rb is webproxy.

When you have a big network to support it is probably better to do webproxy on a faster server.
Many proxy programs can also do more than the built-in proxy of the MikroTik router.
