you really need to look at where your code is spending its time.
the seq stuff I see is quite IO-intensive, sometimes memory-intensive.

it hardly matters. for non-shared clusters, full-on scheduers are massive

let's be honest: they do not provide high values of any metric.
they are relatively slow in any performance metric, low memory,
normally combined with low-performance IO. low power as well,
of course, which is their reason-for-existence.

uh, the field where they are being used: embedded mobile. the point
is that mobile implies dramatic power sensitivity. to some degree,
there are some datacenter-ish workloads that can use ARM effectively -
certain kinds of large-scale web-related in-memory servers. but it's unclear
how much of that is happening yet, since there are infrastructure/packaging
