Test the reading speed of a migration directory

Before starting a migration job, you can use the speed test tool to view the real-time speed for reading data from a migration directory.

Speed test for a Linux system

  1. Obtain the speed test tool from the link: speedTestTool.
  2. Run the ./speedTestTool /dir command to test the reading speed of a migration directory. In the preceding command, replace dir with a migration directory.

    Note: The traffic overhead generated by this tool affects the reading speed for other migration jobs that access the same migration directory. We recommend that you stop all migration jobs for the migration directory before starting the test. This ensures the precision of the testing results.

Speed test for a Windows system

  2. Run the speedTestTool.exe /dir command to test the reading speed of a migration directory. Replace dir with an actual directory.

    Note: The traffic overhead generated by this tool affects the reading speed for other migration jobs that access the same migration directory. We recommend that you stop all migration jobs for the migration directory before starting the test. This ensures the precision of the testing results.
