		perennus on March 23, 2021 \| parent \| context \| favorite \| on: ZGC – What's new in JDK 16 I tried it last week actually with OpenJDK15+Windows. With JDK16, IntelliJ didn't boot. -XX:+UseZGC: Memory usage for my project dropped to a constant 600 megs. Using the IDE felt just as fast as the normal experience. -XX:+UseShenandoahGC, -Xmx4g. Shenandoah GC used a constant 4 gigs of ram. It was a slower user experience for me. In the end, I went back to the default settings, because the custom JDK changes the look and feel and I don't like it.

Shame, I hoped it would feel faster than the normal experience, with (even infrequent) user-felt GC pauses completely eliminated.
