I've recently updated the performance section of a comparison between the Boost Serialization library and the C++ Middleware Writer -- http://webEbenezer.net/comparison.html#perf. The new tests were done on Fedora 12 and Windows Vista. The previous version of that file is here http://webEbenezer.net/comp138.html#perf. The most dramatic change occurred on Windows. Previously the Boost versions were around 2.7 times slower than the Ebenezer versions. Now they are between 3.8 and 4.0 times slower than the Ebenezer versions. I believe that difference is due to our dropping return codes for exceptions. I'm not sure why it shows up more on Windows than on Linux.
Our measurements show Boost.Serialization spends most of its time creating (constructing) archives and there it's mainly initializing the locale... Not sure about the exceptions, I have no related data. Regards Hartmut ------------------- Meet me at BoostCon http://boostcon.com
