Build times

1.

The following build times are done with a fresh stage3 tarball from October 2010. The armv5tel stage3 is softfloat-based while the armv7a is softfp-based. Therefore no CFLAGS have been changed. The portage snapshot is the same for all machines as well, and its located on the USB stick as well.

Important: The USB stick used is the same for all the hardware.

The commands ran to obtain the buildtimes are as follows:

  1. emerge -v screen portage-utils gentoolkit
  2. emerge -vF binutils gcc glibc portage
  3. emerge -v1 binutils gcc glibc portage
  4. qlop -tgHv binutils gcc glibc portage
