Hi! When recently fixing a GCC configury bug uncovered by using dash for /bin/sh, we wondered which build-time benefits the use of dash would actually bring.
kepler is a Xen domU on a AMD Athlon II X2 215 with 2700 MHz, the domU
has 1 GiB of RAM, and is running Debian GNU/Linux testing x86. Debian
packages bash 4.1-3, dash 0.5.5.1-7.4.
coulomb is a AMD Athlon XP with 1466 MHz, has 1 GiB of RAM, and is
running Debian GNU/Hurd unstable x86. Debian packages bash 4.1-3+hurd.1,
dash 0.5.5.1-7.4.

dash 2 h 35 min 10 h 50 min
This data is from one iteration only (I did not repeat the experiment),
but both systems have been idle apart from the GCC build. The build was
essentially a native ``configure && make'', based on GCC Git sources,
master branch, 7c9f953a01d23c6b6885dc908d5b1dba8009efd4 (2011-07-18),
plus a few patches (minor to this experiment).
Grüße,
Thomas
