This is wrong. libtool detects whether you can use bashisms, and falls back to POSIX shell constructs if it cannot use them. The non-POSIX constructs are usually faster because they do not need to fork() the shell. Autoconf does the same. dash rejects some of these constructs, and accept others. Before Autoconf started doing this, dash was indeed quite a bit faster than bash on configure scripts. So your estimate of 50% is valid for projects on which Autoconf has last been run 7-8 years ago.
