# Increase the PDI client memory limit

We recommend that you increase PDI's memory limit so the Pentaho Server and the PDI client (Spoon) can perform memory-intensive tasks, like process or sort large datasets or run complex transformations and jobs. You will need to increase the memory limit for both the Pentaho Server and the PDI client. If you choose to not increase the memory limit, PDI uses the default memory settings that are defined in your startup scripts.

**Note:** Instead of modifying the PDI client startup script, you can also set the environment variable *PENTAHO\_DI\_JAVA\_OPTIONS* equal to *-Xmx2g -XX:MaxPermSize=256m* on your client.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.pentaho.com/install/9.3-install/pentaho-configuration/tasks-to-be-performed-by-a-pentaho-administrator/configure-the-design-tools-and-utilities/pdi-design-tools-and-utilities/increase-the-pdi-client-memory-limit.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
