STRANGE REGULAR SPIKES OF HIGHER LATENCY

Just curious to discover a cause for the regular every hour latency spikes.

V.M. M100 with perfect speed results. S.H.3

These spikes occur with everything switched off. Wireless is permanently off.

I think in the past it has been identified that it is the superhub.

Thanks, will attempt to find the reference.
