Performance issues in split PHP/MySQL installation

We are using PHP 5, Apache 1.3.x and MySQL on Windows. Everything used to be on one server and the site seemed to work well. For business reason we had to movethe MySQL database to another Windows machine near-by. Since the move the time it takes to fetch a page increased considerably. As a first try I replaced the mysql_connect calls by mysql_pconnect. It does not seem to make a difference. So while I try to setup some bechmarking printouts I'd appreciate some ideas how to find the problem and how to improve speed. regards Gabor ps. If I understand correctly on Windows there is only one Apache process, and the thread created to serve the page is recycled immediately. Based on this you cannot actually have persistent database connections using Apache on Windows. Please correct me if I am mistaken.
