You probably mean the execution time of the command itself, right?

That's usually followed by the restart cycle, i.e. all Akonadi processes being 
stopped and restarted.

Or is that actually just taking 3 seconds?

I see.

The thing is such a long delay would usually suggest some kind of blocking 
wait operation, e.g. a D-Bus call timing out.

But akonadictl is using the same interfaces and apparently doesn't block, at 
least not for longer than 3s on average.
