The metrics tests in this directory are designed to be used to assess storage IO.
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.
The blogbench test can be run by hand, for example:
$ cd metrics
$ bash storage/blogbench.sh
The fio test utilises the fio tool, 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.
Test to compare the use of DAX option in virtio-fs.
