First of all, I must apologize for not having the newsletter correctly available last month. Gremlins in the works meant that December's new tips page was not available when the newsletter was sent out. If you missed it, it is here.

Otherwise, I guess the biggest news is Sun saying that EJB performance is unacceptable unless you are really careful in your design. Of course this isn't new - we've been emphasizing this in our courses since we started giving them, and we aren't the only ones to point it out. (Though of course we tell you exactly what is good and what is bad for your design in our courses.) Sun's statement will lead to some changes in EJBs sooner rather than later.

Also noteworthy is the continued acquisitions in the Java performance tool space. Admittedly Symantec acquiring Veritas is not for Java performance management exposure, as that is only a very small part of the Veritas story. But OPNET acquiring the DiagnoSys product from H&W is part of an integrated story - they also acquired Altaworks recently. OPNET are clearly aiming to be part of the end-to-end performance management space, and in that space it is crucial to have a good Java application performance management story.

Wily Technology delivers what you need: Availability, Performance and Control
The most critical web applications in the world are managed by
software from Wily, the leader in enterprise application management

This month we have Kirk with his usual excellent roundup discussing Data Transfer Object pattern, tail recursion, tuning a prepared statement cache, and much more; We have the first new tool report for a while, Enerjy's Memory Profiler (see our tool report page to access previous tool reports); and of course our usual selection of Java performance news and tools.

In addition, this month we have focused on one article for all our new performance tips - and it is not even a Java performance article. This is a sample chapter from "HP-UX 11i Tuning and Performance, 2nd Edition", and the detail and quality of performance methodology tips in that chapter singles it out as essential reading for every performance tuner, whatever you are tuning. So we not only extracted a huge number of tips for you, but also left it as the sole article we present this month.
