- <title>Slow Write Speed on Live Images</title>
-
- <para>
- In one of our previous releases (denzil), users noticed that booting
- off of a live image and writing to disk was noticeably slower.
- This included the boot itself, especially the first one, since first
- boots tend to do a significant amount of writing due to certain
- post-install scripts.

- <para>
- The problem (and solution) was discovered by using the Yocto tracing
- tools, in this case 'perf stat', 'perf script', 'perf record'
- and 'perf report'.
