It starts at startup and then then the latency number keeps increasing as the 
days will be passing. The highest it got was 19 ms and it never got higher than 
that.  The quality of my system never suffered but I am just concerned.

So is both at startup and all the time if it makes sense.

Thanks as always Lonnie

Ionel,

Is this only at startup or all the time ?
