Hi All, we have recently upgraded our production server from version 1.1.0 to 1.4.3. We actually imported the data from old cluster to new cluster with minor data and mapping removals. But as compared to previous version, the performance has been decreased. Many requests returning the time out in response. The application has broken, as we are using it as a source of data reads. Our cluster is having 3 nodes of configurations of 8 core, 60GB RAM. Is there any default settings changes that can cause such side effects. I am facing issues like, search requests are very slow data retrieval after saving is not instant. Please let me know the area to work on. All help or guidance will be appreciated.

That depends on what your settings, your data and your queries are like.

Can you please ask me some specific question on settings,data and queries. So that I can explain.

If you can gist/pastebin/etc your config and query and document samples, and provide some details around your cluster size and architecture, as well as where you are seeing slowness, then it will make the troubleshooting process a lot easier.
