Hello everyone,

After upgrading our environment from Open Distro _1.11_ to _1.12_ version, we are facing issues regarding the **JVM memory usage** :

 ![image](https://us1.discourse-cdn.com/flex019/uploads/mauve_hedgehog/original/2X/b/baf530c32ef210528d75a178179b922cdb2fecd3.png)

The heap usage seems to grow with no reason. The environment resources remain the same before and after the update.

Are there any known issues about this or breaking changes that may cause this behaviour?

Any assistance will be greatly appreciated.

Regards!

Hi @Phandora we have fixed some performance issues in the latest 1.13.1 version, could you try that version here: [Redirecting to /for-elasticsearch/](https://opendistro.github.io/for-elasticsearch/downloads.html)

Thanks.

Hi @zhujiaxi!

We have been checking the changelog for _1.13.0_ and _1.13.1_ versions and we have not found any issues related to the heap performance.  
Could you give us more details about those performance issues?

Thanks.

Hi @Phandora,  
You can reference this issue on the performance issue we fixed in 1.13.1.

> I see considerable Performance degradation between the versions 1.11.0 and 1.13.…0. I do not know which section this issue belongs to so i am opening issue in opendistro-build section. I tried to sample data in both versions on the same machine and view the the dashboard. version 1.11.0 is loading very fast when compared with 1.13.0. The difference is lot. its in seconds.
