<p>The performance test takes a locale and creates a RuleBasedCollator with
default options. A large list of names is used as data in each test, where the
names vary according to language. Each Collation operation over the whole list
is repeated 1000 times. The percentage values in the final column are the most
useful. They measure differences, where positive is better for ICU4C, and
negative is better for the compared implementation.</p>

<h3><i>Notes</i></h3>
<ol>
<li>As with all performance measurements, the results will vary according to
the hardware and compiler. The strcoll operation is particularly sensitive; we
have found that even slight changes in code alignment can produce 10%
differences.</li>

of multi-level sorting, and other features of collation, see <a href=
