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.
