Cognos Report Performance issues using QFS Trace

[damzI]

Hello All,
I have created the QFS trace to determine delayed responses from our reports. I find that the "Request Summary" in the trace does not add up with the intervals between Execution Start Time and Execution End Time. The interval always returns with a greater value than the request summary. Could anyone provide a clue to this mystery.
Thanks,

The timestamps reflect when objects are created and deleted. The period time that an object is alive does not reflect execution time.. The time in Msec of items is Rset attribute or Rs element.
