Install IOzone on Raspberry Pi

IOzone is a filesystem benchmarking tool that evaluates the performance of various file operations in different environments. It tests file input/output (I/O) operations such as read, write, re-read, re-write, random access, and more.

This tutorial demonstrates how to install IOzone on Raspberry Pi.

Install IOzone

Run the following command to update the package lists:

sudo apt update

Install IOzone:

sudo apt install -y iozone3

To verify installation, check IOzone version:

iozone -v

Testing IOzone

To use IOzone, you can execute it from the command line with different options to define the type of benchmark you'd like to run. For instance, the command:

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

It runs all tests (-a) across various 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 the -f option designates the temporary file to be used during the test.

Example of output:

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.
