You've given figures for a typical case. Without worst-case figures, it's premature to declare anything else obsolete, as some of us have to worry about people deliberately choosing to interact via worst-cases to see what fun they can have. You also haven't touched memory stability -- do some situations, while streaming, suddenly cause the available implementations to balloon in memory requirements? There's a lot more than "how fast and how small" to choosing a compression algorithm for many situations beside just "shrink some files somewhere under my homedir". -Phil _______________________________________________ Tech mailing list [email protected] http://lopsa.org/cgi-bin/mailman/listinfo/tech This list provided by the League of Professional System Administrators http://lopsa.org/
