Hmm, I've tested this on fresh -CURRENT and -STABLE UP boxes,
and on SMP bento, and I cannot reproduce this behavior with
new make(1).
It also seems to depend heavily on the location of "src/"
and of the value of MAKEOBJDIRPREFIX. I get best results
with MAKEOBJDIRPREFIX pointing to NFS homedir, but the
result in this case is unstable:
old make new make
/usr/src + 4,99s 29,85s
/var/tmp/ru/obj
/var/tmp/ru/src + 5,05s 29,80s
/var/tmp/ru/obj
/usr/src + 5,48s 14,45s 6,65s
/home/ru/obj
/var/tmp/ru/src + 5,34s 12,84s 2,74s
/home/ru/obj
In any case, this seems to be an issue specific to
this machine, so nevermind this post.
Cheers,
