question about "Queries per second avg"

[C.R.Vegelin]

Hi List,

Using printf(" System status: %s\n", mysqli_stat($link));
in a PHP script, says: "Queries per second avg: 0.051".
This means that a query takes about 20 seconds ?
But the query result is given immediately.
How should I interpret "Queries per second avg" ?
I'm using version 5.0.15 NT.

Regards, Cor
