@eosterlund.bsky.social is publishing a #ZGC book, now's the time to pre-order!

Details below!

Forwarding Tables overhead

@jpbempel.bsky.social spotted spikes in native memory during #ZGC generational (default in #JDK 23) cycles, this happens where’s also a spike in Java Heap allocations. So this might be something to keep an eye on when memory sizing you’re #containers.

As seen on inside.java, my latest blog post "How ZGC allocates memory for the Java heap" details how ZGC works behind the scenes, doing much more than "just" collecting garbage. Available at: joelsiks.com/posts/zgc-he... #Java #OpenJDK #ZGC

Just landed the Mapped Cache in ZGC last week - a project I've been working on for the past 6 months or so. It reduces fragmentation, improves NUMA support and lays the foundation for future enhancements. Check it out at: github.com/openjdk/jdk/... #Java #OpenJDK #ZGC

Some changes in #ZGC memory allocation coming in #OpenJDK 25. This should help transition from shared memory to anonymous mmaps. I guess `jcmd {pid} System.map` will come in handy.

Comparing Java 23 GC types So this is an article in response to the following...

I present to you my article comparing the three GC types on JDK-23:
G1GC, ZGC+Generational, Shenandoah:

(while it applies to #ZGC, Google is exploring this for G1 and Microsoft for SerialGC! awesome collaboration across different vendors <3 )
