The script 'bench_write_req.py' allows comparing performances of write request for two
qemu-img binary files. If you made a change in QEMU code and want to check the write
requests performance, you will want to build two qemu-img binary files with and without
your change. Then you specify paths to those binary files and put them as parameters to
the bench_write_req.py script. You may see other supported parameters in the USAGE help.
