You might wish to dedicate more of that 8 Gbyte to Java, though. It depends on the performance characteristics of your application - looks to me like MySQL is grabbing a load of your RAM for its cache. top (or similar) would confirm that overall usage, and I assume MySQL has some performance monitoring available that'll tell you the effectiveness of its caches. If you're *just* tipping into using swap, it's almost certainly the case that MySQL is grabbing memory that would otherwise be called "free". This may well be the best use for the RAM, but there's a possibility that more RAM dedicated to Java would improve your performance overall. I'm not willing to make that guess without data on the effectiveness of MySQL's cache, though :-). - Peter --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
