## **Recommended Requirements**
Recommended CPU/RAM requirements based on Documents/URLs indexed.
| Documents/URLs | SearchBlox Requires | RAM on Server | Processing Power |
| 0 - 100,000 | 8GB | 16GB | 4 or 8 cores |
| 100,000 - 500,000 | 16GB | 32GB | 8 cores |
| 500,000 - 1 million | 31GB | 64GB | 16 cores |
| 1 million + | Cluster Setup | Cluster Setup | Cluster Setup |
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.
`-Xmx8g`
`-Xms8g`
Change to 16g when you have at least a 32GB server:
`-Xmx16g`
`-Xms16g`
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
`-Xmx8g`
`-Xms8g `
Please restart SearchBlox and Elasticsearch services after saving the changes.
