fio - Flexible IO Tester - Windows example

Posted by neto in Databases on Jan 29, 2013 7:47:04 AM

Hi All,

 

This is neto from Brazil

 

How are you?

 

Doing a performance POC (NetApp - I love this company!) and I have been using fio (https://freecode.com/projects/fio) and it works very well.

 

Here you have one example how to run fio on Windows using raw devices.

 

All the best
