Re: NetBSD 6 is looking pretty good

I have a VLC which is running netbsd-6 from 1-October. It's been
compiling and doing various things for the last two weeks with no problems.
I did notice one thing, though. When running benchmarks/dhrystone/, the
number I got was:
Microseconds for one run through Dhrystone: 569.1
Dhrystones per Second: 1757.2
I would mention that Dhrystone is an extremely poor integer benchmark.
Its limitations were known back in the 1980s and I don't think anyone
takes it seriously.
Here is a much better one (but there are of course many others):
When I ran dhrystone on netbsd-5 earlier this year, though, I got 2164
which is almost 1.25 times faster. What's also interesting is that the
standard number given for dhrystones per second for the VAX 11/780 is
exactly 1757, too. Does this mean that the inefficiencies of new
toolchains has brought a 25 MHz 1991 machine down to the speed of a 5
MHz 1977 machine?
That said, I have a 5 MHz MicroVAX II here running NetBSD 1.4.1 if you
wanted to confirm the latter number. :-)
