Even if we forget everything else you said, "Apache + PHP + PostgreSQL" means you have at least ... BOTE calculation ... at least 24 different combinations of how these components interact with each other and each has different performance characteristics. You need to give us much more information before something meaningful can be concluded. In general, 90% of your performance issues will be in the application (PHP code, not PHP itself) and the database (structure, indexes, etc.). Assuming you have a decent application architecture, database schema and enough bandwidth, can you think of a similar already existing web application so people can have a baseline when giving you advice? (Don't think "Google" ... think of a smaller application which can be compared in size to yours).
