                            ab is the apache benchmark utility i believe it comes with apache. i un debian and know it comes with the debian apache package. so what you put
                            in stresstester.php3 is upto you. i would recomend a series of adding and deleting databases and tables also try to update insert and delete rows
                            from a table too. if you use a -c flag you can set the level of concurency say -c 500 would allow 500 simaltaneous request to that page. this
                            would be beneficial casue you can test mysqls response to having to deal with that.
