R7000 speeds are neutered with MAC address cloning is used

My internet speeds were upgraded considerably the last few months. No matter what I could not get above about 160 Mbits.
I finally factory reset the router. Speeds had no problem reaching 500 MBits. I restored the router settings
using the backup i made right before reset...seeds sucked again.

Long story short I then added each setting back one by one to figure out which one is causing issues and it looks like MAC cloning is the culprit.

If I leave the MAC address alone (use the default router MAC) speeds are fine. If I clone the MAC of a device thats on the network, speeds top out at about 160 MBits.

Is there some process that has to be used for MAC address cloning that bogs the router down under high speed downloading?

It might disable CTF (cut through forwarding) that was needed to hit gigabit speeds on those older devices. Anything that causes packet inspection disables ctf. Maybe thats disabling it for some reason.
