Frequency table on round trip times (RTTs) of
queries.
Each <command>nn</command> specifies the corresponding
frequency.
In the sequence of
<command>nn_1</command>,
<command>nn_2</command>,
...,
<command>nn_m</command>,
the value of <command>nn_i</command> is the
number of queries whose RTTs are between
<command>nn_(i-1)</command> (inclusive) and
<command>nn_i</command> (exclusive) milliseconds.
For the sake of convenience we define
<command>nn_0</command> to be 0.
The last entry should be represented as
<command>nn_m+</command>, which means the
number of queries whose RTTs are equal to or over
<command>nn_m</command> milliseconds.
