+ 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'. + + + + See all the unvarnished details of how this bug was diagnosed and + solved here: Yocto Bug #3049 + +
