I assume you're talking about the Multinet SSH server - I use it all the
time. Even at 7-10 simulated VUPs, the only thing that takes a long time is
logging in. Once you're connected, it's just fine.
How bad would it be at 1 VUPS? ;)

This changes with Phase V, since that doesn't change the MAC address (if it doesn't have to be Phase IV compatible, that is). Also, unlike Phase IV, Phase V supports end nodes with more than one interface.
Can you have different addresses per interface in Phase V?
No, that's an IP mistake DECnet did not adopt. Addresses are node addresses, not interface addresses. The reason Phase V handles multiple interfaces (whether on the same LAN or not) is that it doesn't set the MAC address, as Phase IV does. Instead, the nodes keep a table of node address to MAC address mappings -- analogous to the ARP table in IP, but derived from (a) hello messages and (b) incoming traffic rather than from broadcasts.
Aaaaah. I understand now. Thanks.

Huh.
32-bit binary on 64-bit OS vs native 64 bit binary on the Linux VM's.
I love how the default compiler likes generating 32-bit binaries for some silly reason.

Yup.

Yeah, that might. ;)

In any case, I don't mind the overhead of the small Linux VM underneath them and they will soon all be on a large-ish server in a colo rack as I sell my apartment. Sampsa might leave London, but SAMPSACOM stays behind :)
The large-ish server should definitely help. ;)

KUHAVX got about 12 VUPS when running natively on a Core i5 iMac, 24 when in a Linux VM on the same hardware. Pretty weird.
Really? I've gotten 20 VUPS on both.
Which version of OS X?
10.7.5 (Darwin 11.4.2 Darwin Kernel Version 11.4.2: Thu Aug 23 16:25:48 PDT 2012; root:xnu-1699.32.7~1/RELEASE_X86_64 x86_64)

Interesting.
Which version of SIMH and do you remember to SET CPU IDLE?

And yes set cpu idle was specified on both, in fact the ini files are identical except for network adapter name changes.
