We already extracted the tips from "Crunching Big Data with Java" by Jim Falgout in last May's newsletter, but a reader pointed out this quote from that article, which I thought worth repeating here.

A note from this newsletter's sponsor

Improve your code profiling in development and you'll improve your
Java-based applications. Read "Performance Analysis in Eclipse"
to learn a proactive strategy for better testing directly in Eclipse.

"Granted, I know I may lose some edge of performance using Java. It's true that in C I'd have more control of memory and so could utilize cache line sizes and other tricks, such as processor affinity, to get better performance. But for programmer productivity, it's hard to beat Java when used with the IDEs available today, not to mention the rich libraries that are available. I'm willing to trade a few points of performance to write an application in Java over C given how much more productive I can be in Java. Java is portable, fully object-oriented, easy to code, and used widely. For all of these reasons, the dataflow framework used to implement the matching application discussed in this article is written in Java - otherwise it would have taken my team much longer than a month."

I think this is a pretty accurate distinction, the best I've read. There is not much difference in performance between Java and C, except when you want to do some esoteric tricks - the kinds hackers love but that make maintenance hell. Java wins hands down in almost every case.

Now on with this month's newsletter. We have our usual lists of Java performance tools, news, and articles. At fasterj we have a new cartoon Caching remote objects; Javva tells us about No. 1 and, as usual, we have extracted tips from all of this month's referenced articles.
