Now on with this month's newsletter. This month at fasterj we look at optimizing the performance of java.util.regex regular expressions. And, of course, we have our usual news, article links, tools, and extracted tips. Javva the Hutt tells us about his Weekly Meeting; and we have extracted all the tips from those articles.

News

Java performance tuning related news.

• concurrency proposals for Java 7 include: TransferQueue; multicore-friendly lightweight parallel framework; scalable counters; ConcurrentIdentityHashMap; better atomics support for fine-tuning of memory model effects; algorithmic improvements to java.util.Collections.
• GlassFish version 2 monitoring capabilities
• The -Xintelligent_as_can_be_execution and -Xcompletely_brain_damaged_execution are valid options - but they don't do what you expect
• xSocket 1.2 NIO-based library released
• Java 7 update: Doug Lea is working on a Java 7 update to the JSR 166 java.util.concurrent utilities. His fork/join package is a concurrency framework for cleanly dividing tasks up for efficient concurrent execution on the multicore CPUs of the future.

Tools

Java performance tuning related tools.

• xSocket is a easy to use NIO-based library to build high performance, highly scalable network applications.
