Slow Write Speed on Live Images
|
|
===============================
|
|
|
|
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.
|
|
|
|
The problem (and solution) was discovered by using the Yocto tracing
|
|
tools, in this case 'perf stat', 'perf script', 'perf record' and 'perf
|
|
report'.
