m1-test MacBook Pro 2016 & AMD EPYC 7642 Test Result

晚上看见测试视频，我觉得蛮有意思，自己也找不同环境的测试了一番包括Sun JDK11，Zulu JDK16

在我的MacBook Pro (15-inch, 2016) 的测试成绩如下：配置信息： CPU 2.7 GHz 四核Intel Core i7 OS：Big Sur 内存：16 GB 2133 MHz LPDDR3 JDK：OpenJDK Runtime Environment Zulu16+59-CA (build 16-ea+24) mvn clean -T 1C -Drat.skip=true compile -offline

从监控上看，mvn还是很难利用服务器CPU这么多核心并行编译，基本上就是利用了4个C左右 M1 从多线程性能上肯定比不过96线程的服务器CPU，只是说在相对线程数量不多的情况下，优化的确不错

可以再做一些更多的benchmark，common-lang的代码还是太少

赞👍. 一开始也是想测大的代码库的. 最后找的小代码库, 一方面是这样能够节省我太多时间(我每个test都要跑多遍), 另一方面, 代码库大了编译过程会很吃内存, 而两台电脑的内存差得很远, 容易引入噪音. 用小的代码库, 两台电脑的内存差异成为最后performance差距的dominant因素的概率就小很多。(当然, 应该也是可以通过设置heap max size来控制这个因素)。

Test more JVM parameter

GC使用了CMS/G1/ZeroGC（JDK16已经去掉了CMS GC）
JVM 测试了-client和-server，-server能快100ms 通过参数，可以控制编译common-lang的时候使用CMS不发生GC，因为的确很小的一个class编译

使用默认的G1GC

如果不指定-Xms和-Xmx，会发生16次GC，但是影响就是100-200ms

-Xms4096m -Xmx4096m 发送3次GC，暂停<100ms

[INFO] Total time: 4.417 s (Wall Clock) [INFO] Finished at: 2020-12-16T11:38:46+08:00

使用CMS

-Xms4096m -Xmx4096m -XX:NewSize=1536m -XX:+UseConcMarkSweepGC -XX:MetaspaceSize=512m -Xlog:gc* 不发生GC Total time: 4.381 s (Wall Clock)
使用UseZGC（Zulu JDK16）### 更慢，跟我理解不符合 -Xms4096m -Xmx4096m -XX:+UseZGC -Xlog:gc*

有没有简单的JAVA的运行性能测工具测试呢

Feb 28 '21 14:02 zh-h

如果是测试服务端性能，可以用JMeter https://jmeter.apache.org/ 可以配置各种参数做性能压测。不过需要你先启动个Server起来，相对而言基本上没有什么Java的桌面应用程序，一般而言，除了像Intelli IDEA等
