# Kata Containers storage I/O tests
The metrics tests in this directory are designed to be used to assess storage IO.
## `Blogbench` test
The `blogbench` script is based on the `blogbench` program which is designed to emulate a busy blog server with a number of concurrent
threads performing a mixture of reads, writes and rewrites.
### Running the `blogbench` test
The `blogbench` test can be run by hand, for example:
```
$ cd metrics
$ bash storage/blogbench.sh
```
## `fio` test
The `fio` test utilises the [fio tool](https://github.com/axboe/fio), configured
to perform measurements upon a single test file.
The test configuration used by the script can be modified by setting a number of
environment variables to change or over-ride the test defaults.
## DAX `virtio-fs` `fio` Kubernetes tests
[Test](fio-k8s/README.md) to compare the use of DAX option in `virtio-fs`.
