sPHENIX tracking discussion

Hi folks,

until fairly recently the clustering (which I tend to call electron 
drift) took about as much time as the G4 simulations themselves. As of 
recently the time of this pass has increased by at least a factor of 2 
and I see hijing jobs with 400 MinBias events exceeding the 3 day limit 
which evicts those jobs so we only get calorimeter clusters from these 
sims. You can see the timers in a log from a jobs which finished today:

The PHG4TpcDigitizer is by far the biggest contributor now.
