Proposed changes

Switch kernel frequency to 1000hz from 250hz, as 250hz was a holdover from the P4-ish era. This allows much better throughput and PPS, and also aligns us with most other distros HZ settings.

Hi @xrobau,

this is the same as #161. Please ensure your commit has a valid headline. I took to opportunity to alter the headlines from #161 to match our CONTRIBUTING guidelines. It is also always a good idea to check a files history what other maintainers used as the commit headline.

This is nothing to make your life harder, this is to make our life easier in the future when we revise changes why certain things became as they are.

Well that didn't work well. How about this?

LGTM

My comment is not about the change itself, it is about the formal process of using a good commit message which helps us in the future. Can you please reword it?
