Maybe our system just showing it age. Design decision at the time they was made are good but it's no longer true. It's time to change, if we are willing to change. There are plenty of reference sources, from both Linux or the BSDs.
I have always noticed that Solaris (and OpenIndiana) is slower to fork processes than Linux or FreeBSD. It seems slower to enlarge the process address space as well (perhaps because it does not lie). Regardless, I run configure scripts under OpenIndiana and Linux very regularly and the performance difference is not nearly as large as you describe.
Using ksh93 (the normal /bin/sh shell) should be the fastest, although our version has some bugs which are currently being addressed by an update.
In the past I have compiled BSD ash (Also known as 'dash') under Solaris and I noticed that configure script run much faster than with bash.
A long time ago I profiled executing configure scripts using Dtrace and posted the results to the GNU Autoconf list. Due to the findings, Autoconf was made a good bit faster for all systems.
There is often a common implementation element which is taking a large portion of the time. For example, if 'sed' was slow, then that could cause a big slow down.
