> Cassandra often return response in less then < 1 ms
> from another datacenter
> [default@test] get sipdb[23];
> Returned 0 results.
> Elapsed time: 219 msec(s).
> from own dataceter
> [default@test] get sipdb[13];
> Returned 0 results.
> Elapsed time: 0 msec(s).
> Precession of this timer needs to be increased a bit, while looking at network latency
adding 1 number should be enough like : 0.2 ms should be sufficient. 
> It would be good to display sub milliseconds only if time elapsed is < 1 ms.
