Subject: tickless and HZ=1000 throughput advantage?

On tickless kernels, is the general consensus that for non-embedded
systems, selecting HZ=1000 gives slightly more throughput in
particular situations than HZ=100 or 250, due to finer timer
intervals/granularity?

(low HZ used to cause problems with low-rate QoS packet queues when
timer scheduling was selected)

Thanks,
  Daniel
