Both text-mode Linux and GUI and text-mode Windows versions are included. The results of multiple tests are summarized into a single OpenDoc format spreadsheet, readable under OpenOffice, LibreOffice, or Microsoft Excel. FIO is required to perform the actual IO tests. Please ensure the latest version is installed, either from your operating system's repository or sources available at https://github.com/axboe/fio or precompiled for Windows at https://ci.appveyor.com/project/axboe/fio (for the GIT latest) or from https://www.bluestop.org/fio/ . (There seems to be an issue with FIO 3.1 under Windows that is not present under earlier or later builds. In a nutshell, the 1200 second sustained performance test ends up running, under this version, for over 12 hours! While the final results are still good and the script continues, it does waste a large amount of time and so I recommend avoiding the BlueStop 3.1 build. The CI.appveyor.com link above can be used to get current FIO head builds instead.) ------------------------------------------------------------------------ A new --cluster option allows for running multiple clients in parallel, to allow testing performance of shared storage systems like SANs or AFAs. Start a "fio --server" job on all clients, then on one of them run ./ezfio.py --cluster --drive host1:/dev/dr1,host2:/dev/dr2/... ... Basically add "--cluster" to the command line before the drive option, and in the drive option make a comma separated list of hostname:/path/to/storage . The first host in the list must be the one you're currently running ezfio from. ezfio will try using the local system to collect appropriate system info on the first drive. In the current implementation, all nodes/drives must be identical in size. There are no provisions for having volumes of differing sizes. All other graphs and results should be the aggregate of the entire cluster, as reported by fio. ex: Start up FIO servers on all systems to be tested (on host 1): # fio --server & (on host 2): # fio --server & (on host 3): # fio --server & Run a benchmark run: (on host 1) # ./ezfio.py --cluster --drive host1:/dev/nvme1n1,host2:/dev/nvme1n1,host3:/dev/nvme4n1 ------------------------------------------------------------------------ ezFIO got where it is today through the help of many users who filed bugs when things didn't work, or submitted patches to support new CPUs. Please feel free to open issues or drop me a line if you have questions. Special thanks to @coolrecep (Recep Baltaş) who has spent literally days tracking down Windows issues.
