= Benchmarks

All benchmarks were created using `unordered_set<unsigned int>` (non-duplicate) and `unordered_multiset<unsigned int>` (duplicate). The source code can be https://github.com/joaquintides/boost_unordered_benchmark[found here].

The insertion benchmarks insert `n` random values, where `n` is between 10,000 and 3 million. For the duplicated benchmarks, the same random values are repeated an average of 5 times.

The erasure benchmarks erase all `n` elements randomly until the container is empty.

The successful lookup benchmarks are done by looking up all `n` values, in the their original insertion order.

The unsuccessful lookup benchmarks use `n` randomly generated integers but using a different seed value.
