JDK 11 improves by around 5% and JDK 18 by around 18%, respectively, compared to JDK 8 延迟： 设置最大停顿时间为 200ms As you can see, the throughput scores increase significantly simply by moving to later JDK releases. JDK 11 improves by around 5% and JDK 18 by around 18%, respectively, compared to JDK 8 设置最大停顿时间为 50ms JDK8 200ms JDK11 200ms JDK18 200ms JDK18 50ms Average (ms) 124 111 89 44 P99 (ms) 176 134 104 56 Relative collection time (%) n/a -15.8 -34.4 +0.06 内存占用 With JDK 8, after a short warmup period, G1 native memory usage settles at around 5.8 GB of native memory. JDK 11 improved on that, reducing the native memory footprint to around 4 GB; JDK 17 improved it to around 1.8 GB; and JDK 18 settles at around 1.25 GB of garbage collection native memory usage. This is a reduction of extra memory usage from almost 30% of the Java heap in JDK 8 to around 6% of extra memory usage in JDK 18. 升级 JDK 版本的 V 友说一下系统性能提升大吗？ 哪里能看到最新的 G1 性能对比？
