Pressflow 7

IS there a way to compile Pressflow with HipHop for PHP ?

I would like the most performant Drupal because I have to enable a lot of modules in it (when I say a lot, my modules folder contains currently 333 projects), and the site will have to handle with a huge number of users and contents.

I am planning out a solution using master-slave replication, possibly with Pressflow 7, and wanted to do a reality check that the approach makes sense. I'd greatly appreciate your feedback, even though my use case is not particularly high performance.

My client uses a browser-based application to do data collection in remote locations. These 'satellites' have web access about once a week. Currently, they are dumping a SQL file, emailing it, and manually updating the master server. Ideally, the master and all slaves will be kept up to date with the complete DB as much as possible.

Olá a todos.
Tenho estado um pouco afastado do drupal, de certa forma também devidoa frustração da demasiada fraca performance em servidores partilhados.

É óbvio que não posso esperar ir dos 0 aos 100 em 5 segundos com uma lata velha, mas custa-me não poder usar o drupal para os meus pequenos projectos.

Já usei vários métodos de cache (so não usei o varnish, não tenho direitos para tal) e nunca fiquei satisfeito com os resultados.
