我是帝八哥, 过来和你建立一个连接，哈哈

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

在一台48线程96核的AMD EPYC 7642 服务器上

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

1. the funny things is why do you run apache with Java?
2. post together with your speed test photo maybe better
3. you make not very know about the power of i9
   as you are using the notebook Lv CPU if you get the new i9 10000K
   ARM will still lost!
   It doesn't means I'm the intel fan's but if you really wanna make the good test you should peer with ADM
   I'm also the hardware and software engineer.
   It doesn't means you are going the wrong way we most care more about the probuct running on the client site for sale.
   the JDK of MSFT cuz same get some bug for the other process.
   May be this is for your test, but it should not going to work for the stable developer.

Hi,

Not sure had you tested the Liberica JVM for M1?
https://bell-sw.com/pages/downloads/#/java-11-lts

They do provide a stable M1 JVM
https://download.bell-sw.com/java/11.0.11+9/bellsoft-jre11.0.11+9-macos-aarch64-full.pkg

Nice if you can do a test on this JVM. Not only that the JVM come with JavaFX as well.

Thanks and best regards
Ivan

I remember you recommended a terminal hyper in a video, and I guess you should customize the software appropriately because the default settings are a little too simple. Can you tell me how you customize it?

In addition, I recently found a similar terminal terminus, also very useful.

我在想是不是M1是ARM架构的，本身比X86架构在这点上有优势，因此我在huawei cloud上开通了kc1.2xlarge.2 实例
CPU Huawei Kunpeng 920 2.6GHz 8vCPU
内存 16G

• openjdk version "1.8.0_242" Result
  华为自带
  编译选项：
  增加 -Xms4096m -Xmx4096m
  mvn clean -T 1C -Drat.skip=true compile

• 使用zulu JDK15 （无JDK16 Linux ARM版本）

GC策略G1

JDK15默认慢一些，而且比我的Macbook Pro 16 2016款更慢
华为自带JDK不认 Unrecognized option: -Xlog:gc*

• this issue is only for recording what I fell about ur video. and yes, I just wanna say hi.
