I don't know what you tested, but I don't see a substantial speed up on
running autoconf-generated configure scripts:
# time SHELL=/bin/bash CONFIG_SHELL=/bin/bash /bin/bash ../configure ...
# time SHELL=/bin/dash CONFIG_SHELL=/bin/dash /bin/dash ../configure ...
Another, more extensive test case:
In other words, I am observing a 5-10% speed up on running autoconf
