BFE>Performance of boost::circular_buffer on the standard tests in my book is competitive with std::vector, and at least five times as fast as std::deque or std::list on the same tests. This is not surprising given the similarity between the implementation of circular_buffer and vector. I also performed tests to assess the performance of list, deque, and circular_buffer when used as a queue. As expected, the circular buffer outperformed list and deque.
