Certainly possible; I have no visibility into what's actually
in there. But it seems to have about a dozen drives, which
ought to give a decent amount of bandwidth ...

douc isn't running the TAP tests, so it's not directly comparable.
But I don't find that a 25-minute BF cycle time without TAP tests
is impressive.
Anyway, I would be happy if someone would put forward evidence
refuting my results, and even more happy if community members
trying to work on this patch had access to AIX hardware that
wasn't ridiculously slow. As things stand right now, I have
zero motivation to continue working on it.
