performance bottleneck analysis
I read this on finding bottlenecks (https://www.win.tue.nl/promforum/discussion/365/finding-the-bottleneck
have some further doubts. Is it always necessary to mine a control flow
(say in the form of a petri net) to do performance bottleneck analysis?
Cannot it be done using the log data itself without extracting a
for example, suppose my event log has <ID,EventName,Timestamp> as follows:
<1, A, t1> <1, B, t2> <1, C, t3> <1, D, t4>
<2, A, t5> <2, C, t6> <2, B, t7> <2, D, t8>
i not simply subtract the times for consecutive steps based on the ID
such as t2-t1 for events, B,A for trace 1? The maximum differences
should give the bottleneck(s) right? Or is it too simplistic?
Where can I find more about why exactly the two steps of petrinet/workflow extraction and replay required?
