Test the reading speed of a migration directory

Before you start a migration job, you can use the speed test tool to obtain the speed of reading data from a migration directory.

Speed test on a Linux system

1. Download the speed test tool.

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

   Note

   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 on a Windows system
