Tuning System Requirements
CPU and RAM requirements are a recommendation.
Requirements may vary based on volume of documents, number of collections, refresh frequency, and number of search users.
## **How to update the memory for SearchBlox and Elasticsearch?**
By default 8 GB RAM is allocated to SearchBlox and 4 GB to Elasticsearch. Therefore minimum 16 GB RAM is required to run SearchBlox.
Update the memory allocation in Windows by editing the `
<SEARCHBLOX_INSTALLATION_PATH>/start.ini` file within the SearchBloxServer folder.
Change to 16g when you have at least a 32GB server:
Update the memory allocation of elasticsearch by editing `
<SEARCHBLOX_INSTALLATION_PATH>\elasticsearch\config\jvm.options` and updating xms and xmx value in line numbers 22 and 23 as shown below
Please restart SearchBlox and Elasticsearch services after saving the changes.
