copy and paste from the typo3.org website: "As a piece of software, Typo3 is a collection of PHP4 server-scripts, HTML-documents and gif-files arranged in folders on a webserver. In addition Typo3 utilizes the MySQL database.
The demands on the webserver capacity is that it should have a very fast processor and lots of RAM in order to generate the website graphics on-the-fly. Also the serverload should probably be moderate, so that peakloads with graphics involved do not pull down the server. It should be noted that the performance of Typo3 has proven to be fine so far on fast Pentium-servers. " plus the site mentions it has not been tested for scalability. else, php-nuke would have been our choice ages ago. we are exploring non-php based solutions, so far. LL
