JEP 546: Adaptive Heap Sizing for ZGC
Enhance the Z Garbage Collector (ZGC) to adaptively adjust the size of the heap based on the resources available, the application's needs, and the needs of neighboring applications contending for the same resources.

After working on ZGC for a decade, I’m happy to announce that I’m publishing a book about ZGC in JDK 25. It ships 22 May (www.taylorfrancis.com/books/mono/1...) and is being published by Taylor & Francis. You should get a copy if you want to learn more about ZGC. It’s available for pre-order now.

"Gemeinnütziges Zentrum für Gesundheit und Chance“ (ZGC)
Quasi eine Vorfeldbezeichnung für KZ, wenn ich das richtig interpretiere.
Anlass: AfD Düsseldorf hatte den Plan, in der Bergischen Kaserne Asylsuchende und suchtkranke Obdachlose verpflichtend zentralisiert unterzubringen.

📝 Blogged: "Let's Take a Look at... Lower Java Tail Latencies With ZGC"
As #Java 25 got released earlier this week, I took the ZGC garbage collector for a spin, exploring how it lives up to its promise of sub-millisecond GC pause times.

JEP 545, Faster Startup and Warmup with ZGC, is now a Candidate! Complementing Leyden AOT for startup and warmup, ZGC reduces the trade-off between fast startup with a small initial heap and smoother performance with a large, pre-touched heap 😀

不知道为什么chatgpt和deepseek都说zgc占用只多百分之几，java21 mc实测下来占用多太多了，而且zgc在内存不足的时候会特别卡，比g1gc多分配2g堆内存还是个位数帧数

This is my first time traveling on a refurbished Z24500 (this one is from the AURA region), and it looks fantastic
The refurbishment program for TER trains across France (AGC/ZGC/BGC, TER2N, and TER2NG) is quite impressive—not a cheap undertaking! ☝️

Do you trade off startup and warmup by tuning -Xms, -Xmx and -XX:+AlwaysPreTouch appropriately? And did you set -XX:+UseTransparentHugePages together with the appropriate shmem_enabled kernel config? Me neither. ”JEP 545: Faster Startup and Warmup with ZGC” is candidate now: openjdk.org/jeps/545
