I think I understand why sessions are evil but for snappy client user experience I don't want to have to re-query the database on each HTTP request. (As a comparision, Java servlets can effortlessly keep tons of session objects in memory.)

Can PHP be set to do this or does it have to serialize because it runs from CGI/FastCGI and therefore by definition is a new process each time a request comes in? I will be running PHP using LAMP.
