I suspect it's to do with all the extra stuff added into the strcache; as I mentioned before, it turns out that every temporary filename we construct for pattern rule searches goes into the strcache even if they don't match anything: that's a lot of extra memory. I wonder, if you run make (both old and new) with the "-r" flag, if you'll see similar divergence in performance. -- ------------------------------------------------------------------------------- Paul D.
