Your database communication, queries and data will have to be very, very heavily optimised if you want to hit this target - or you'll need some heavy iron to run it. How large is the dataset on which you're working? Can you simply load it all into working memory? Looking up data in memory is typically thousands to hundreds of thousands of times faster than running a database query. If it's only a few gigabytes, you may well find it's cheaper to spend on adding RAM to your cluster than on solving the problem any other way! - Peter --------------------------------------------------------------------- To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
