It entirely depends on what you are trying to do with pl/Perl however. If you need access to tuple data (ability to modify records etc...) then your kind of out of luck. However, if you are using it to perform logic and then spit back the results pl/Perl could be very useful and give a speed increase. The speed increase would come from only returning the results of your calculation versus returning a set of data and then performing calculations on that set and then displaying it.
