So, check my understanding: what you're saying is that, in your

No. I consider a CDC-6600 or a PDP-10 or 4.2BSD a dinosaur.
VAXen and m68k machines are already mammals. ;-)
Since 4.2 ran on VAXen, how do you get that? :-)
I say: If you run current operating systems on old hardware, you have
accept that it doesn't run that fast as a 10 year old version of that
And I can't really see a compelling reason for why it should be so. But
that's just me, I guess.
Why should newer always equal slower?
And given all those VAXen around me I certainly don't want to cut
support for VAXen in NetBSD.
Also: We VAXherds are not the only users of NetBSD. There are other
users with other priorities, other interrests and faster machines like
Alpha, UltraSPARC and even PeeCees. Refusing to import "bloat" that
those people want, _need_, only because it slows down our old VAXen, is
a bit unfair.
True, in a way. But I think it's wrong to make the division between
owners/users of modern hardware vs. old hardware. It's rather a division
between people who want one set of features and functionality vs.
another set of features and functionality.
There are problably those using VAXen (as well as new hardware) who
would want all that Linux and Windows have.
And then there are those who would not. Who perhaps would prefer a
system that still used ASCII, or possibly Latin-1. Who don't want PAM,
LDAP, and any number of features that they consider are just a burden
which is unwanted and unneeded. Unfortunately, there are less and less
choices for that group of people to select from.
Every current OS is trying to mimic everyone else. The thing is, if
that's what you want, there are already a number of existing choices for
you to pick among.
Also #2: DEC pulled the plug of the VAX architecture 15 years ago and
replaced the VAX with Alpha. DEC did this because it was clear that the
VAX couldn't compete with the rest of the industry. It was slow even
bak in the late 80ies. (Compare a VAXstation 3100 againt a DECstation
3100 or a SPARCstation 1...)
Well, 15 years ago is a bit exaggerated. The last orders for VAXen were
accepted in 2000. That's a bit over 8 years ago now. And it was COMPAQ,
and not DEC by that time.
And as far a speed comparisions, that's difficult. The speed range of
the VAXstation 3100 series is very wide. The 3100/76 is pretty ok.
And that one is contemporary with the SPARCstation 1, I believe.
