Timing measurements

• All jobs run in batch to guarantee 100 CPU
• l3fmuo_unpack version v00-03-02
• Release t01.28.00-maxopt on d0mino
• Files Z-gtmumu and Z-gtee from Serbans area,
  d0sim_p05, 200 events each
• Total time running time from l3statmanager and
  SpeedShop agree, comparison of functions from
  SpeedShop

Conclusions

• Main time consumer is TKeyfind
• (30 ms or 70)
• Logging info/errors takes 4 ms, can be switched
  off
• Actual unpacking takes less than 10 ms
• speed-up of 4 ms seems in sight
