Root Analysis
New Root Event Structure
- our first shot was attractive structurally, but sloooow
- had consult from Rene Brun and have implemented v2 of structure. Release is imminent.
- [eliminate maps; eliminate pointers crossing subsystems; separate I/O branches]
> x2 faster, now allows selective reading of subsystems
- x20 speedup if calorimeter excluded
probably another factor 2 easy to get
