IOzone

IOzone is a handy tool for testing filesystems. It helps you generate and measure different types of file operations. The cool part? IOzone works on various machines and operating systems!

Why Use IOzone?

So, why should you consider using IOzone? Well, it's super useful for getting a good look at how a computer's filesystem performs. It runs benchmarks that test file I/O performance for several operations like:

• Read


• Write


• Re-read


• Re-write


• Read backwards


• Random read


• AIO read/write, and more!

Key Features of IOzone

Iozone has some impressive features:

• ANSII C source code


• Slick POSIX async I/O support


• Mmap() file I/O capability


• Both single and multiple stream measurement options.


• Distributed fileserver measurements (Cluster)


• Pthreads support for multi-processing


• Easily importable output to Excel for graphs!


• The ability to create latency plots.
  
  
  (And much more!)
  
  Large file compatibility
  
  Configurable processor cache size
  
  Selectable fsync and O_SYNC measurements
  
  Builds available for AIX, BSDI, HP-UX, IRIX, FreeBSD, Linux...you name it!
  
  
  

The Importance of Benchmarking Filesystems

If you're thinking about buying a new computer or upgrading one you have, understanding the filesystem performance is key. Over time, people often change the types of applications they run on their systems. While some vendors optimize their OS to work well with certain apps (like databases), others may not perform as well.

This can lead to frustration when users find their system is slow with new applications! By running tests with IOzone, you can spot any hot or cold spots in performance and choose a platform that's more balanced.

NFS Read Latency Graphs

The NFS3 Read Latency graph shows how quickly your system can handle read operations over an NFS Version 3 filesystem using IOzone. You can also take a look at the Re-read Latency graph to see how caching impacts performance.

What's New?

This latest release has added new dedupe testing support! Plus, there are fresh options like -+w and -+y to explore.
