Configuring JVM Settings for the Search Process

If you're using On-premise Search, you can configure the heap, ports, logging path, and other settings for the Java virtual machine (JVM) that runs the Search process.

For a list of the settings you can adjust for On-premise Search, refer to the Startup Property Reference.

Note:

Best practice is to set minimum and maximum heap sizes to the same value.
The heap size you set for the Search service is independent of the heap size you set for the web application.
