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: http://lists.boost.org/Archives/boost/2005/07/90814.php http://lists.boost.org/Archives/boost/2006/03/102133.php 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.
