In terms of worst case figures, these plots look a bit like what I've seen
with RT-Linux and RTAI on various hardware (PII/III workstations via Geode
SBCs through Intel Core based Celerons on industrial Mini-ITX boards), though
with "true" RT kernels, one tends to get a lot of very low latency points, and
only the occasional peak.

SBCs with lowpower CPUs (Geode and the like) tend to perform a lot worse than
"proper" laptop and desktop CPUs. Memory and/or cache bandwidth issues, maybe?
