Can anybody help with this? Java is much better in terms of resources than PHP, at least this my experience. It is not only much faster in my opinion, it has better tools to do profiling. I really did both on a high traffic website (600 accesses per second at peak time) and we solved almost any problem we had with java/tomcat/hibernate/postgresql vs apache/php/postgresql. In my experience, hardware is never an issue, at least not in the beginning. Most bottlenecks i have seen are software related. beginning at the database level with proper indexing and configuring the database, configuring the connection pool, using a cache, profiling your app will offer valuable insights. And not to be forgotten: take a look at the client with Yslow Firefox plugin. A great tool. And take thread dumps of you virtual machine at peak time to see what is really happening. So don't guess, measure! kind regards Janning Thanks Jan - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

Re: Multiple apps on single server
Two things: 1 - Use Brix. You can write your ecommerce components as tiles that can be rearranged however you want in any site. You can create plugins for the admin console for management of said ecommerce shops. 2 - There's absolutely no way anybody on this list can answer your question. I've been to enough different businesses to know that those numbers are entirely dependent on how you use the said frameworks. You can use them efficiently, or not. You can have large object graphs, or not. Etc. You'll just have to see. But I can tell you this: there are a lot of high-traffic Wicket applications out there running on a single server of the capacity you mention. Assuming you hit a load barrier, it's likely going to be the database first - so offload the DB to its own server. That just increased your capacity.
