Timing Measurements for the second Level Trigger software of ATLAS with TrigTimeAlgs

Timing measurements for the ATLAS LVL-2 trigger software performed with the TrigTimeAlgs package [1] were studied. The reproducibility of the latency of a typical algorithm was measured under constant conditions. The measuring procedure is described and a method is proposed to improve the reliability of timing measurements (minimum method). The results of timing measurements with the latest nightly release (08-28 2003) are shown.
