There's been a noticeable slow down in the arm and arm64 latency of
late. I tracked the issue
down to the tracing infrastructure. For now if you hit this issue,
disable ftrace. Once this is done the latency numbers look much better.
I'm currently working on resolving the issue.
New patches will be released this week for both arm and arm64 now that
the issue is understood and a work around exists.
