Manually Set Max Memory

Many times Realfire deals with huge files (either to read, analyze export) which demands lots of memory size. While most of the times, you don't need to manually set memory but sometimes you need to based on the tasks at hand. This section walks through how to set the memory manually.

By default, Realfire allocates itself the good amount of memory depending on the physical memory available in the machine. For ex., one of our executorTest machine has 16gb memory and in that, Realfire allocated itself about 4gb.

You can check the maximum memory configuration used by Realfire using the Memory Meter. This is a widget that is shown at the bottom of the application window. If you hover your mouse and hold above the area for a couple of seconds, the tooltip popsup and shows the details.

For ex., in the screenshot below, the maximum memory assigned to Realfire is 4096M, which is about 4GB.

To Manually set the memory, follow the below steps.

  1. Quit Realfire Application

  2. Open the realfire.ini file in a text editor. This file is located in the application installation folder as below.

    • Mac: {InstallationFolder}/
    • Widnows: {InstallationFolder}/Realfire/realfire.ini
    • Linux: {InstallationFolder}/Realfire/realfire.ini

    InstallationFolder varies from system to system depending on where the application was installed.

  3. Add the line -Xmx1024m to below the line -vmargs. Change the value 1024 to a number indicating the number of MBs of memory to assign. For ex., if you want to assign 8GB change that to 8192.

    After changing the file should look like below.

  4. Restart the app and check the Memory Meter. It should show the new max memory.
