nstream Performance

Performance test

This is very quick performance test of various string streams. In this test we write random integer into string and read it back from that string and make sure that initial and resulting numbers are equal. The contestants:

• Standard istringstream/ostringstream
• boost::iostreams with sink and source described in boost::iostreams tutorial
• nova::stream with in_buffer_provider and out_buffer_provider described in sections "Writing input stream with in_buffer_provider" and "Writing output stream with out_buffer_provider" with minor change in out_buffer_provider to implement small string optimization.

Here are the result:

stream	Execution time (ms)	Compiled size (stripped)
stringstream	6002	8224
boost::iostreams	4567	24704
nova::stream	3890	8272
