Mikrotik hAp ac Lite and VPN slow speeds

As per thread title.

I am playing around with Mikrotik ROS software, and quickly set up a dummy network to cap the user's speed, etc. And using an LTE router as the WAN interface.

But I have noticed that when I connect to a VPN server in the US, to route the device's traffic through to the other side, it seems like I only get like 300kbps instead of 10+mbps, on mobile data.

What am I doing wrong? Is there a mangle rule that I need to set up? Or add some routing entries?

This seems like to be a common problem online, and a big mixed bag solutions and rules, which none seems to be working...

I have tested with OpenVPN, UDP and TCP. Same result. Slow connection.

But if I remove the Mikrotik router out of the picture and connect directly to the LTE router, VPN speeds shot up to 15+ mbps...

Have a look at your CPU load while doing a speed test.

System -> Resources -> CPU

Try using a different VPN protocol like IPsec or PPTP (Unsafe) and play with the encryption ciphers.
