One way is to load-balance Tomcat instances behind Apache using mod_jk and sticky-sessions. You can also use a hardware load balancer as well. There are a number of options here which will work. > 2) Does clustering helps in this situation? If yes, any reference on how to > implement > that? (I dont mind reading esp. when it is new to me) Clustering Tomcat (see the docs) will allow you to move users from a failed Tomcat instance to another without losing the user's session state. > 3) Does Apache play any role in this improvement scenario?

You may be able to serve that load easily on your existing hardware, or you may not be able to come close. It depends on the type of load your app generates. You should be able to estimate how much more load another 10k users will generate based on your existing load of 2k users and go from there. -Dave --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
