I did some tests with NOGEOM and NOSEC. The results pretty much confirm
David's tests. But there are a few results I don't understand which
I list here:
(note: David and I have different PCs, only ratio makes sense not
absolute speed).
1. With all on default 8:30/100 events
(8 minutes and 30 seconds per 100 events)
I used the same files (generated by Will) as David did
2. NOGEOM 'All' 0:04/100 events
3. NOSEC 'ALL' 0:56/100 events
4. NOSEC 'MINI' 'TORU' 'EC' 'EC1' 'DC' 'FOIL' 'SC' 'CC' 5:20/100 events
5. NOGEOM 'MINI' 'TORU' 'EC' 'EC1' 'DC' 'FOIL' 'SC' 'CC' 0:20/100 events
These results are repeatable to within 5-10 seconds level.
I checked BEG_RUN_SUMI, the summary T & F were set to what I asked.
Magnetic field appears to be on in all cases sicne I could see
curved tracks when I asked for displaying tracks.
Questions and puzzles:
a. Why tests 3 and 4 are so different? What other componets we have besides
the listed individual ones?
b. What about 4 and 5.
Any experts can offer me some hints?
