It used to give significant boost for automake & libtool based software
- however at some point libtool started to use bashisms and so you
cannot just replace /bin/sh -> dash - as build will fail.
(zsh doesn't seem to boost the speed)
My test cases do not involve libtool, just autoconf and automake
generated files.
Also I said - upto 50% - which depends on complexity of configure files.
The complex case involves 47 recursive configure scripts and 329
automake-generated Makefiles ;)
But even your personally measured 10% speed is in my eyes pretty
significant if you do builds all day and surely outweighs some RAM (and
IMHO even RAM will be actually still positive anyway on dash side if you
do parallel builds)
I do not share this view. IMO, reliability outweighs this speed up.
Provided Fedora doesn't have any experience with dash, I am very
reluctant on claims concerning dash.
