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.
