Ok, 

posting this discussion to the mailing list. 

My RTIA provides no statistics. How can i enable this feature and possibly
all other debug messages (see my previous mail to the devel mailing list).

Thema	[bug #25497] NextEventRequest to a timestamp smaller than last grant time + lookahead

Follow-up Comment #13, bug #25497 (project certi):

OK then,

I think the previous "non-working" patch wasn't working
because the zero-lookahead code from Pierre was broken
at that time.

It was broken because of me :-(

Thus it appears that the non working patch *seems
to be working* now that zero lookahead is un-broken.

Concerning the lack of performance, I suggest you 
open another bug/feature entry and/or discuss this
issue on the ML.

It would be interesting to know thenumber of messages
sent/received by your federate, please copy paste
CERTI message summary found at the end of each federate
run.
