-<h1>"Multimap" Text Insert Timing Test with Small Average

- Secondary-Key to Primary-Key Ratio</h1>

-<h2><a name="description" id="description">Description</a></h2>

-<p>This test inserts a number of pairs into a container. The

- first item of each pair is a string from an arbitrary text

- [<a href="references.html#wickland96thirty">wickland96thirty</a>], and

- the second is a uniform i.i.d.integer. The container is a

- "multimap" - it considers the first member of each pair as a

- primary key, and the second member of each pair as a secondary

- key (see <a href="motivation.html#assoc_mapping_semantics">Motivation::Associative

- Containers::Alternative to Multiple Equivalent Keys</a>). There

- are 400 distinct primary keys, and the ratio of secondary keys

- to primary keys ranges from 1 to 5.</p>

-<p>The test measures the average insert-time as a function of

- the number of values inserted. For <tt>pb_ds</tt>'s containers,

- it inserts a primary key into the primary associative

- container, then a secondary key into the secondary associative

- container. For the native multimaps, it obtains a range using

- <tt>std::equal_range</tt>, and inserts a value only if it was

- not contained already.</p>

-<p>(The test was executed with <a href="http://gcc.gnu.org/viewcvs/*checkout*/trunk/libstdc%2B%2B-v3/testsuite/performance/ext/pb_ds/multimap_text_insert_timing_small.cc"><tt>multimap_text_insert_timing_test</tt></a>

-<h2><a name="purpose" id="purpose">Purpose</a></h2>

-<p>The test checks the insert-time scalability of different

- "multimap" designs (see <a href="motivation.html#assoc_mapping_semantics">Motivation::Associative

- Containers::Alternative to Multiple Equivalent Keys</a>).</p>
