I blogged about this 2 years ago when I first started using cwrappers,
along with a bunch of other pkgsrc performance stuff I was doing at
tl;dr for me cwrappers reduced a bulk build from 12 hours to 5hr 20m.
Since then I've been able to do a full bulk build in under 3 hours
with further tweaks, and without cwrappers I certainly wouldn't be
able to get anywhere near that, as one of the key benefits for me with
a lot of parallel builds is the hugely reduced system time.
