CPU Latency Changes

[stevefxp1]

Hello all,

Tuned is changing the CPU latency from 1000 to 100 and back, every 30 seconds or so. Is this a normal process? I would assume this is bc I am running dynamic? I guess I should change to static?

Thanks,
Steve

It should adjust the QoS according to the load, so probably your load is changing. It's done by the dynamic tuning. It shouldn't happen if dynamic tuning is disabled (the default setting).

I moved to turn off dynamic tuning and will watch it...thanks for the response.
