Can someone (Ingo?) recommend me CPU scheduler tests which are usually
used to test CPU scheduler perfomance, context switch performance,
SMP/migration/balancing performance etc.?
Thanks in advance,
Kirill

it's not really the microbenchmarks that matter (although they obviously
are part of the picture), but actual application performance. There are
dozens of workloads that matter. Kernel compilation timings are an
obvious priority :-), but there are other things like SPECsdet, STREAM,
dbt3-pgsql, kernbench, AIM7, various Java benchmarks and more.
now that scheduler changes have calmed down somewhat, we are mainly
looking for regressions, and are checking schedstats output to see how
'healthy' a given workload behaves.

Do you keep the results available somewhere they can be browsed?
