There was a dip in volume of Java performance related articles earlier this year. Not a huge dip, but enough for me to notice from my regular trawl. Then it pushed back up and now it's back to normal levels; and the ongoing quality is excellent.

A note from this newsletter's sponsor

In the ten years I've been writing and publishing this newsletter we've had previous noticeable dips - always at times of serious worldwide economy problems; both the dot-bomb crash and the credit crunch crash resulted in big dips in article volume. Sadly, it's a lagging indicator, so I can't use it to predict anything; instead, the dip a couple of months back and subsequent rise suggests that either "credit crunch II, the continuing saga" is over and people haven't quite noticed yet (wouldn't that be nice!), or more likely that I'm about to see another dip in volume.

Regardless, there have always been enough tools, news, and articles to fill several newsletters, which means I get to idiosyncratically choose what I put in here. And now on to those idiosyncratic choices, with all our usual Java performance tools, news, and article links. We also have a new cartoon over at fasterj.com measure that your change actually fixes the bottleneck and, as usual, all the extracted tips from all of this month's referenced articles.
