The locale initialization can be avoided if your application can get away with using the boost::archive::no_codecvt construction flag. (Assuming that's still behaving the same as when I looked into this performance area back around boost 1.33.)
These threads may also be of interest:
Based on that link I tried it as follows: int const binary_archive_flags = boost::archive::no_header | boost::archive::no_codecvt; filebuf fb; fb.open("ofile", ios_base::out); binary_oarchive oa(fb, binary_archive_flags); clock_t start(clock()); oa << lst; clock_t end(clock()); I didn't discern any improvement to the performance of this test from adding those flags.
I don't see how that is relevant.
I keep promising myself that I will soon collect sufficient round tuits to
do something
about this, but so far those promises remain broken. Maybe once I upgrade my team to boost 1.41.
