Pause For Thought part 2 ....oracle

In an AskTom thread about native compilation, a poster mentions that he is seeing some big CPU waits on his system and wonders whether native compilation would help. After some discussion of tracing and profiling and his 32 Tuxedo connections, he reports back that from talking to the programmer (possibly this guy), he might have narrowed the problem down to a procedure called DELAY():

I just happened to talk to the programmer and what i understand is that that specific function when called so many times , it is internally calling a procedure with passing a value n, where n is like 4,5,6 etv. That procedure is called delay and its job is to create a delay in the logic flow. So the delay procedure accepsts values like 10 as seconds and then it

FOR di IN 1..sed LOOP
  NULL;
END LOOP;

A random thought, could this when run so many times accumulate huge cpu?

Tom thinks maybe it might.

Thanks Tom for sending this in.
