Yes, you are incorrect. There is nothing that requires an area here, and it just means you need to deal with a full blown DECnet stack, instead of a simpler endnode.
It might be worth understanding that there is nothing technical added by going to multiple areas. It is just a complication which allows you to have more nodes, but at the cost of more complex routing.
Even within one area, you can have a large number of hops between nodes. Makes no difference to DECnet. The rules for the topological layout is simple:
1. End-nodes needs to be adjacent to atleast one level 1 router.
2. All level 1 routers in an area must be able to talk with all other level 1 routers. And only level 1 routers route messages within an area, which means you cannot have an endnode in the chain.
The layout can be a star, a ring, a line, a combination, hybrid, or whatever. There are absolutely no topology that you can't have.
The type of links can also be anything. Ethernet, multidrop, point-to-point, or something weird. Makes no difference.

I'm talking about the DECNET for Linux MULTINET UDP tunnelling..

With Multinet you can run DECnet over TCP in the same
DECnet area.

How was simh compiled? I used Visual C and the difference between running the compiler with optimization on or off made quite a difference for the generated code. And gcc might compile even faster codefiles.

Why is SIMH so slow though?
As far as I can understand, one MIPS is roughly one VUPS, correct?
So how come I get 14 VUPS on the same host running SIMH whilst my Hercules install peaks at 180?
Are the architectures that different (obviously they are) or what is it?

This seems like a natural for SIMH, since it already has a large
amount of necessary prerequisites (a lot of device emulation,
framework pieces, etc.).
There is Alpha support in the development track version of simh.
Is the architecture well enough defined in
publicly available documents? I would guess yes but I don't know for
sure. Are there secret bits that are critical and hard to obtain?
The architecture manual pretty fully documents it.

If the "fiddling" is similar to what is necessary to run VMS on the white box alphas then have a look at
http://home.zonnet.nl/hvlems
The white box alphas were tergeted at the WNT market. Adding two srm parameters works wonders for VMS. It does not involve hardware mods and AFAIK the mods are completely reversible.

Dave did the Alpha family come in a 1U size?
Yes, the DS10L comes to mind. My HECnet node AXPEE:: is one of those.
They are EV6-based (nice and quick!) and are available clocked at
466MHz and 600MHz.
There are other 1U models, but that's the one I'm most familiar with.
If so could said system be considered to be a quiet one?
Eh, so-so.

Well, this is definitely a size/noise tradeoff, at least in many
cases. For low noise, you generally want large-diameter, low-speed
fans. For fans small enough to fit into a 1U enclosure, neither of
those are attainable, so you end up with the little screamers.
