Okay, here we have the bad, bad case – see other mail for good and
a bit bad case (was not yet fully throttling):

I had these with several hundred events... maybe be a bit lower due to
lowering Akonadi load by increasing innodb_buffer_poolsize from 80 to 512 MiB.
But just guess work.
I did have CPU throttling with ACPI and ondemand too. I don´t think as much
as with PState, but still.
Thanks,
Martin
