We built the T-Mobile ecommerce with Struts 1.0.2 with EJBs and an Oracle 9i database ( <http://shop.t-mobile.com> http://shop.t-mobile.com) and get about 15,000 hits/day on a 2-platform multiprocessor cluster of Compaq servers using BEA WebLogic 6.1SP2. We have had no problems with overloading or denial of service. Perhaps the problem is in your code or implentation?

Keep the most accessable tables near the appservers (or even on the same machine). Also, cache and preload the data with high access rate. All these advices are applicable on any java application. There's even a book, Java Performance Tuning. Regarding Struts, we had no performance issues connected directly to it. -- [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
