I've pushed another version to launchpad ( lp:~bwy/+junk/gnash-devel ) that uses a second index of case-insensitive keys. This has the same behaviour as before, and keeps all changes internal to PropertyList. The branch also uses string_table::key for DisplayObject names. Together the changes speed up the swfdec testsuite run, which I've been using as a rough benchmark, consistently by about 10 seconds, or 3%. A possible memory and maintenance optimization would be to have a special caseless map just for objects in SWF6 and below instead of always storing an extra key. It would save sizeof size_t bytes per property and make the code cleaner, but needs better testing of mixed versions. bwy -- Use Gnash, the GNU Flash Player! http://www.gnu.org/software/gnash/ Benjamin Wolsey, Software Developer - http://benjaminwolsey.de C++ and Open-Source Flash blog - http://www.benjaminwolsey.de/bwysblog xmpp:b...@xabber.de http://identi.ca/bwy
