Josh measured against Libtool 1.5.x.  Libtool 2.2.2 has a lot less
overhead in compile mode than 1.5.x, see the numbers Ross posted, and
the list archive of libtool-patches for several improvements including
numbers; and we are currently working on improving things a bit more,
targeting improvements that help all shells which support XSI
extensions (and falling back to the slow code for other shells).

While the multi-thousand line script can't get as fast as dolt -- after
all, dolt isn't portable to non-bash, also there's functionality that
libtool compile mode offers that dolt doesn't -- we expect compile mode
to become fast enough that the overhead shouldn't be a big problem for
practical use, and we expect that to come without the need for users to
change their configure.ac scripts at all.

Meanwhile, updating to 2.2.2 would be a good idea, its link mode has
also become considerably faster than 1.5.x at least for some use cases.
We would appreciate bug reports for particular remaining performance
bottlenecks.

Cheers,
Ralf
