I've recently updated a page -- http://webEbenezer.net/comparison.html comparing results obtained using Boost Serialization (1.48) and the C++ Middleware Writer (1.13) on both Linux and Windows7. There's an archive that has all the test files mentioned on that page here -- http://webEbenezer.net/comp/tests.tar.bz2 . In order to build the tests, you would need to build the Boost Serialization library and an Ebenezer library yourself. There's an archive on this page that has the Ebenezer library -- http://webEbenezer.net/build_integration.html . To summarize the results, the Boost versions range from 1.1 to 3 times slower than the Ebenezer versions. And the sizes of the Boost executables range from portly to obese compared to functionally equivalent Ebenezer executables. Comments on the how to improve the tests/process/etc. are welcome.
