Hi,

I've read monitoring.html from the new documentation and I do not 
understand some points :

- what are the units of the counter "large tuples" ?
- how do you find that it took 0.108s to process the SYNC 19
- what are the differences between sync_event and sync_helper (it should 
be great to add it in the documentation, and in the code)

thanks
