> I don't know if this is the desired behaviour but all the comments in the code indicate
that it should be reporting microseconds. 
> A single write shows the following:
> {code}
> WriteLatency
> ------------
> Count: 1
> Min: 315.853
> Max: 379.022
> WriteTotalLatency
> -----------------
> Count: 339667
> {code}
> In LatencyMetrics:
> {code}
>     /** Total latency in micro sec */
>     public final Counter totalLatency;
> {code}
