Install IOzone on Ubuntu 24.04

IOzone is a popular benchmarking tool designed to measure and analyze the performance of file system input/output (I/O) operations. It helps in evaluating various file system performance aspects, such as read, write, re-read, re-write, random access, and more.

This tutorial explains how to install IOzone on Ubuntu 24.04.

Install IOzone

Update the package lists:

sudo apt update

Run the following command to install IOzone:

sudo apt install -y iozone3

We can check IOzone version as follows:

iozone -v

Testing IOzone

To use IOzone, you can run it from the command line with various options that specify the type of benchmark you want to perform. For example, the command:

iozone -a -I -s 102400 -r 1024 -f /tmp/iozone.tmp

It performs all tests (-a) across different file operations (read, write, etc.) on a 100 MiB file (-s 102400, where 102400 is in KiB) with a record size of 1 MiB (-r 1024). The -I option enables direct I/O, bypassing the system cache, and -f specifies the temporary file to be used during testing.

Output example:

        Auto Mode
        O_DIRECT feature enabled
        File size set to 102400 kB
        Record Size 1024 kB
        Command line used: iozone -a -I -s 102400 -r 1024 -f /tmp/iozone.tmp
        Output is in kBytes/sec
        Time Resolution = 0.000001 seconds.
        Processor cache size set to 1024 kBytes.
        Processor cache line size set to 32 bytes.
        File stride size set to 17 * record size.
                                                                    random    random      bkwd     record     stride
