Hello!

 

Can you please explain what is the issue you are experiencing? Here are few of the recommendations given by the tool (under PRO plan):

  1. It looks like you are using G1 GC algorithm. If you are running on Java 8 update 20 and above, you may consider passing -XX:+UseStringDeduplication to your application. It will remove duplicate strings in your application and has potential to improve overall application's performance. You can learn more about this property in this article.
  2. This application is using the G1 GC algorithm. If you are looking to tune G1 GC performance even further, here are the important G1 GC algorithm related JVM arguments
  3. -XX:+UseGCLogFileRotation argument is not recommended to be passed. It can have undesirable effects. To learn more about it's effects and alternative solution refer to refer here.
  4. -XX:+UseCompressedOops is not required to be passed, if you are running in Java SE update 23 and later. Compressed oops is supported and enabled by default in Java SE 6u23 and later versions. For more details, refer here.
