I'll add a 'unified_rw_reporting' option to be able to do that. Most accounting is done collectively, so it should be pretty simple to do this. -- Jens Axboe Thank you so much! I am starting to use FIO for all my performance POCs here. I hope to have this option as soon as possible ... So I can demonstrate next week. One question: I am doing a PCO using Windows, and if I download all changes via github how can I compile for Windows?
