Well, the most make(1)-intensive test I can think of is make index, so some results from a quick test: hydra# uname -a FreeBSD hydra.bayofrum.net 9.0-RELEASE FreeBSD 9.0-RELEASE #7: Sun Apr 22 21:02:48 BST 2012 root@hydra.bayofrum.net:/usr/obj/usr/src/sys/HYDRA amd64 hydra# cd /usr/src/usr.bin/make && make NO_SHARED=yes && cp make ~/bin/make-static >& /dev/null hydra# rm make && make NO_SHARED=no && cp make ~/bin/make-dynamic >& /dev/null hydra# file ~/bin/make-* /home/chris/bin/make-dynamic: ELF 64-bit LSB executable, x86-64, version 1 (FreeBSD), dynamically linked (uses shared libs), for FreeBSD 9.0 (900044), not stripped /home/chris/bin/make-static: ELF 64-bit LSB executable, x86-64, version 1 (FreeBSD), statically linked, for FreeBSD 9.0 (900044), not stripped hydra# cd /usr/ports && time make MAKE=~crees/bin/make-static index Generating INDEX-9 - please wait..
