How many utilities are to be converted? 4KB (or 38KB) can add up quickly. > But not knowing what compile options you used, or having information > about sizes (and working sets - just listing file sizes is hand waving) > across the libxo modified binaries, this still doesn't give a complete > picture of the relative cost of the feature. Default 'make buildworld' options with CPUTYPE?=core2. So, -O2. I also tested with CFLAGS+=-static in w(1) and ls(1)'s Makefile. The numbers that I showed are from 'make buildworld'. The only difference is w(1) and ls(1) with/without the libxo change. I don't need to cook the numbers to fabricate some issue. Choose your favorite CFLAGS. Use svn to get w(1) and ls(1) with/without libxo. It's not difficult. -- Steve
