If your only concern is performance, then using stored procedures might be overoptimizing. It’s true that they cut down
onoverhead, but that overhead might be meaningless in terms of overall performance. For instance, if you have low
latencybetween your web server and database server, and your typical query takes 5-6 seconds to execute, then most of
yourusers’ wait time is due to execution time, not to communication between servers. Stored procedures won’t help you
much.

If you’re building a simple web site, I suggest starting with what seems simplest for you (which sounds like raw SQL
fromyour description) and then addressing performance problems as they arise. Stored procedures are one tool in the
performancetoolbox.  

good luck
