I have some questions about the CPU core assignment for the different tasks in dd-wrt.

1. It looks like you have no core pinning of the processes, but they just use a core that is available, is that correct?

2. Taskset is not included in dd-wrt, what is the easiest way to install it (or something similar)?

3. There is a kernel parameter to force the system to not schedule any task on a certain core, would this parameter work with dd-wrt?

I see that openvpn, that is my most cpu intensive task, jumps around between the cores. To jump between cores always means a cache penalty and I want to eliminate that.
