RE: [PHP] what PHP really needs

Very true, but tests I've done in the past with PostgreSQL and MySQL-driven PHP sites show that adding a simple static file cache (for data that changes rarely) can make a world of difference on a heavily-loaded site, trimming response times by 90% in some cases. A database server by nature must assume that all data is equally mutable. An application developer, however, knows by design how "fresh" any one piece of data needs to be and can cache accordingly. E.g., don't hit the database for your site's navigational structure or news articles every single time, if these things don't change more than a few times per week. --------------------------------------------------------------------- michal migurski- contact info and pgp key: sf/ca http://mike.teczno.com/contact.html
