The sysbench fileio prepare
command is a command-line instruction used with the sysbench
benchmarking tool.
When running a benchmark on file I/O operations, it is important to prepare a set of files that will be used by the benchmark. The sysbench fileio prepare
command performs this preparation step.
This command generates a specified number of files, each with a defined size, within a specified directory. These files are filled with random data, simulating real-world file content. The purpose of this step is to create a set of files that the benchmark can use for read and write operations.
The sysbench fileio prepare
command typically requires several arguments, such as the directory where the files will be created, the number of files to be generated, and the size of each file. By specifying these parameters, the command prepares the file system for subsequent file I/O benchmark tests.
