This month JavaPerformanceTuning.com brings you a scoop. Our intrepid reporter has been chasing this story for the better part of a year, and now we can bring you the true story of the creation of Java in this month's interview with James L. Frank. You don't want to miss this!

We bring you our usual selection of articles from around the web. Three stood out for me. Firstly, O'Reilly have made available in PDF form chapter 12, "Distributed Computing" from my book Java Performance Tuning. In the current edition this chapter includes optimizing a Java Web service, and it is well worth reading.

The second article that stood out is Steve Trythall's article about optimizing security performance for JMS. Articles that provide useful new tips on security performance are few and far between, so I always find these tend to stand out.

Finally, Intel has produced an article entitled "Enterprise Java Performance: Best Practices". The article itself is quite good, but what makes it stand out for me is the historical context. The last time Intel produced an article covering Java performance (in 1999), it had two tips in it: use Intel chips; and write the code in C using the JNI to call it. Thankfully, Intel is now taking Java more seriously.

Our other regular sections are here too. Firstly, we have that amazing interview about the creation of Java - don't miss it! And our question of the month on Java performance vs the performance of other computing languages will simply astonish you.

We have Kirk discussing various micro-benchmarks, the usefulness of threads, capacity planning, J2EE caching and more in his roundup of discussions; Javva The Hutt researchs JUnit tools for performance testing, and includes his diary; we have a new tool report on Piper, a pure Java caching solution for dynamically generated web pages; and, of course, we have over 100 new performance tips extracted in concise form.
