To tune the application for high performance, please allocate the recommended amount of CPU and memory based on your documents, number of collections and number of search users.

1.) Start by verifying the amount of memory utilized by SearchBlox and Elasticsearch

## **Verify Memory Allocation**

  • You can verify the memory allocated to SearchBlox in the Admin Dashboard license page

517


## **Verify Elasticsearch Memory Allocation**

  • You can verify the memory allocated to Elasticsearch using the URL: https://localhost:9200/_nodes/jvm?pretty=true The heap memory allocated in bytes is displayed.

640


## **Improve Concurrent Collections Indexing**

  • If you plan to run multiple collections simultaneously you can increase performance by increasing the jetty thread values in `<SEARCHBLOX_INSTALLATION_PATH>/start.ini`

  • By default, minThreadPool count is 20 and max ThreadPool count is 100. We recommend increasing the thread pool count as shown below for multiple collections with larger datasets.

  • Update start.ini with the following snippet at the end of the file and restart the SearchBlox service.
