The ARMs look good. I'm not sure about the X86_64: The 'VPS' are
'shared' but I haven't found any information what exactly they share
(shared cores?). Additionally some 2016 reports say the VPS use
Intel Atom cores and only the more expensive 'Bare Metal' plans use Xeon
Cores. I haven't found any official information on the homepage though
so we might have to ask or just try and check available CPU
resources / build speed.

I'll try to setup a local builder for debugging later this week or next
weekend and see if I can reduce some bugs.

OK, then this is something to look into (a lot) later. I guess buildbot
should allow setting up custom sub pages so there's likely some way to
implement a per-branch overview.
