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
Run the
./speedTestTool/dircommand to test the reading speed of a migration directory. Replacedirwith an actual directory.NoteThe 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 you start the test. This ensures the precision of the testing results.
Speed test on a Windows system
Run the
speedTestTool.exe/dircommand to test the reading speed of a migration directory. Replacedirwith an actual directory.NoteThe 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 you start the test. This ensures the precision of the testing results.
