Hello No fastpath, I'll have a look at that.

I have some mikrotik routers constantly running 100% CPU on encryption, this does not seem to be affecting any other traffic going through the routers. But as most of your CPU is on routing/firewall that will affect other traffic. Are you using FastPath?

We are a very small wireless ISP (around 2000 customers) and run MikroTik router kit (I know I know...) I can see its normally firewall and routing process's that use most. Running around 300mbps on the routers in question. I can certainly upgrade, just wasn’t sure if it was worth it. MikroTik don’t have much kit that is small and runs 24v.

For a more instant view of the CPU, do a "show proc cpu history", this will show you the spikes (assuming csco). Assuming the box you are using is not just under-powered, you need to look at what is hitting the cpu and see if you can control/remove it. Chasing "links that don't seem to go as hard as they should", oh man, that's such a can of subjective worms......
