An application based on Oracle 10g
Has following strange scene:
In singleUser API test,
delete a Item will take 700ms, which is normal.
But delete a folder will take 2s! which is unacceptable.
Opatch info:
bash-2.05$ opatch lsinventory

the trace shows a total elapsed time of 0.43 sec

1) make sure there are no triggers that add processing not shown in the trace file (I seem to remember that triggers don't show up in trace??)
2) Read YAPP (signup first)
