As usual just before each Java release, I'm listing all the new performance features in the upcoming release of Java 17 (I have done this every 6 months prior to each new release, you can track back to the previous February and August newsletters if you want to see what's new performance-wise in any release). As usual I give the new features, the performance benefits from each feature, and how to use the feature.

Java 17 has a bunch of performance changes, but nothing really major. This is expected, because Java 17 is a Long Term Support (LTS) release, and no one wants to make a significant change in that release because if it's wrong, you have to support it for a long time. Instead all the significant changes are in the Java 12-16 releases, where they've had time to be well tested before Java 17.

Now on to the details of those Java 17 changes, including the options you have available to use them. And of course the tips from this month's articles, as ever are extracted into this month's tips page.
