Experimenting with `fio` - Flexible I/O tester on NFS vs fsdax

See https://github.com/osalbahr/pmem-redirection

I experimented with fio, a well-known tool for I/O benchmarking. Here are some simple benchmarks with the following target files:

  1. $HOME/fio.txt - Network Filesystem (NFS)
  2. /mnt/fsdax/$USER/fio.txt - Persistent Memory (PMEM)
  3. /tmp/$USER/fio.txt - SSD (note: I called the job in the jobfile "ram-tmp" incorrectly, it should be "ssd-tmp")
