Short answer: *less than 2 secs*
Long answer:
In order to measure the time added to do_rootfs by the
gtk-update-icon-cache calls, I modified gtk+ recipe to create a wrapper
script, as seen in attachment [1].
I compiled core-image-sato using the following setup:
CPU: Intel(R) Core(TM) i7-2600 CPU @ 3.40GHz, 4 cores with HT
RAM: 8GB
Storage: SSD
The measurements are in attachment [2].
Conclusion: I would say that a delay of less than 2 seconds added to
do_rootfs is not that bad, in my opinion. Of course, we can optimize
this as much as possible but, is it worth the effort?
You could give it a test yourselves and let me know your results. I will
send a version 2 of the patchset(as soon as we all agree on the
solution), with some changes suggested by Mark and some PR bumps
suggested by Koen.
[1] - measure_time.patch
[2] - do_rootfs.log
Thanks,
Laurentiu
