Updated resource for tuning Java performance

Question

Can someone recommend a website that contains up-to-date performance recommendations for Java? Most of the sites that I found seem to be old, and I think that newer versions (1.5 - 1.7) may have outdated some recommendations.

Edit:

I mainly focus on reducing memory usage / garbage collection and ensuring that simple methods can be built in if necessary.

This code involves processing large amounts of data in streams using a large number of small objects. For each data item, some objects are created, others longer. These objects typically implement an interface or extend an abstract class.

Update: For me, a reference document for setting up a Sun virtual machine: Java SE 6 HotSpot ^TM Configuring a Garbage Collection Tuning virtual machine (this will also give you a methodology).

As noted in the comment, the ergonomics function does a good job of configuring a modern JVM and should be tried first before checking for more detailed control.
