I couldn't find anything related to TPTP either. It has huge "Average 
Base Time (seconds)"  value for such method which is 0.046532 and it is 
called only 1713 times.

But what I can see now XModel thing just first reason of performance 
issues IMO. We must do something and clean it up. It just loads 
processor without any reasons. I see calls counters is growing up even I 
just sit and do nothing.
