# cut -d \| -f 2 ${PORTSDIR}/INDEX* | while read d; do cd $d && make -V ALLFILES | tr " " "\n" | grep -v '^$' || : ; done > current-distfiles
# find ${DISTDIR} -type f | grep -v -f current-distfiles | xargs rm

Compile a list of the distfiles from INDEX, then delete everything not on that list.

The default command seems to use all the CPUs. Might want to try specifying -j - yeah, that works:

[0:38 mydev dvl /usr/ports] % time sudo make -j 36 index

Interesting, with 72 or 36, it's the same elapsed time: 13 minutes.

There is no need to generate the INDEX locally, INDEX file are generated by the project and can be fetched from within the ports tree by command make fetchindex. See /usr/ports/Makefile for the target internals.
