[PERFORM] Trigger is taking time to fire

[Ramasubramanian]

Hi All,
    I am having a trigger in table, If i update the the table manually it is 
not taking time(say 200ms per row), But if i update the table through procedure 
the trigger is taking time to fire(say 7 to 10 seconds per row).

How can i make the trigger to fire immediately ?

Regards,
Ram
