I can also reduce the number of times _have_rc_postprocessor is called.
Thanks. I can make comparison tests on some classic hardware, as soon as a
new patch is available.
I just added a patch to PR 50046. It makes _have_rc_postprocessor
much cheaper (I think it should not fork at all), but doesn't
reduce the number of times it is called.
I think this would be quite important to fix for 7.0, as it affects all
hardware with a weaker CPU. And NetBSD runs on a lot of this hardware
(embedded, NAS, etc.).
Oh yes, it's essential that we fix this.
