 We have only 100,250,300 and 1000 values for CONFIG_HZ.

I didn't know for shaping.
I think there is now far less modem connected with native ADSL traffic, most
have switched to ethernet layer.

I have too lowered CONFIG_HZ as a safety against lost interrupt that will
probably happen with some ethernet not napi drivers.

I have look at Ubunbu server config and they have CONFIG_HZ=100 and a few
users that complain for related side effect.

So I am afraid we need a compromize.


Do you agree for CONFIG_HZ=250?
