Here is the result of a fairly big build for ARM (X.org, Gtk2, WebKit,
Midori), on a fairly big machine (quad-core, 12 GB of RAM), build was
done with BR2_JLEVEL=16, and the build does not include a toolchain (I
used an existing internal toolchain).
Without debugging symbols
=========================
* Real time: 51 minutes
* User time: 200 minutes
* System time: 14 minutes
* Size of output directory: 3.4 GB
* Size of staging directory: 445 MB
* Size of target directory: 102 MB
With debugging symbols
======================
* Real time: 58 minutes
* User time: 232 minutes
* System time: 16 minutes
* Size of output directory: 9.0 GB
* Size of staging directory: 2.0 GB
* Size of target directory: 102 MB
So, I'd say we should drop my patch 2/4.
Regards,
Thomas
