[Libguestfs] [PATCH nbdkit v2 0/3] filters: stats: More useful, more friendly

[Nir Soffer]

- Use more friendly output with GiB and MiB/s
- Measure time per operation, providing finer grain stats
- Add total stats for understanding system throughput
- Add missing stats for flush

I hope that these changes will help to understand and improve virt-v2v
performance.

Changes since v1:
- Keep bytes values
- Increase precision to 0.001 GiB and 0.001 MiB/s
- Add total stats
- Show time before size/rate for more consistent format
- Streamline using new record_stat() and print_stat()

v1 was here:

  filters: stats: Add flush stats
