time spent for iteration

Is it possible to add timer for the time spent for iteration when iterate operator or the delta iterate operator is performed?

thanks

Yes, I also think that it would be a nice feature. It would make the
advantage of delta iterations (that later iterations take less time)
more visible to the users.

I think it would be useful to allow for easier retrieval of this
information.
Wouldn't it make sense to expose this to the web UI for example?
We actually had a discussion about this some time ago [1].

Hello,

If you increase the log level, you can see each step of the iteration
separately in the log, with timestamps.
