# Single Threader The Single Threader step executes a sequence of steps in a single thread, which allows you to tune the performance of your transformations by limiting the number of threads or processors used: * To solve issues in transformations with many steps by reducing the data passing and thread context switching overhead. * To sort data rows in a specific time frame or by a specific number for real-time streaming. * To process chunks of data, pause, and then continue processing after reaching the chunk size.

Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.pentaho.com/pdia-data-integration/10.2-data-integration/pdi-transformation-steps-reference-overview/single-threader.md?ask= ``` The question should be specific, self-contained, and written in natural language. 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.
