I think it would be equally interesting if you posted benchmarks for MySQL 4.1.x Since the last post comparing MySQL 5.x vs 4.1.x on FreeBSD showed that MySQL 4.1 series had almost double the benchmark performance numbers over 5.x MySQL I couldn't bare the idea of using MySQL 5 if its still only half as fast and has features I don't need. I believe most people would prefer 4.1 unless they really need the features that are in 5.x or don't need performance at all. Mike
