Hi folks,
I was (rightfully) questioned about using the term lower rate, I'll
attempt to clarify as that's incorrect.
What the hires_tick setting does is reduce the interval of when data is
sent. Same amount of data, just sent in smaller chunks, over a smaller

You can check what it's running at by do:
cat /boot/config-kernel | grep HZ
Where kernel is the version you are running
Examples:

Hi Kevin,
Most likely thing is that the new switch is not successfully negotiating
full-duplex on the ethernet link. It really kills throughput and ...
potentially leads to collisions (which gets you packet loss). You should
