My recollection, for what that's worth, is that it has something to do
with the proprietary ethernet driver (that I/A uses to implement COMEX,
etc.) not being multithread/multicore capable.
Virtual machine -- I'm ambivalent about that. On the one hand, it's an
ugly hack to fix the multicore problem. On the other, if it's the first
step in running I/A completely in a VM, then that's a good thing IMHO.
This single-core issue makes me wonder (again) if any significant number
of people at Invensys have thought about doing a clean-sheet redesign of
I/A, to incorporate lessons learned over the years and free themselves
from the constraints of legacy design decisions with respect to more
recent changes in the automation and IT landscape. Maybe that's what
Infusion is ultimately supposed to be, I don't know. It's a daunting task,
and a business gamble, but a couple of I/A competitors I know of did it
awhile back, and it's paying dividends for them now in terms of
flexibility and capability.

Frits,
Yep - it's IA that requires you dumb down to a single core. Pure InFusion
with no IA can use muli-core. My understanding from the 2011 users
meeting is that they are working on running IA in a virtual single core
machine so you don't have to turn off all but one core. They hope to have
that ready about the same time as 8.8 is released but have not tied it to
that release.

We are talking IA here...
