we want to build a website that have some forms (including image attachments, info, etc…) online payments, tracking system, and other features that I may add later.
The number of users using the site is estimated to be maybe more than 50,000.
I’m using WordPress to develop regular websites, but I’m afraid to use it in this project because I don’t know how optimized is WordPress for high database usage (and page rendering, bandwidth usage, and …)
My options (those that I know) are:
- WordPress
- Drupal
- Pressflow
- Agility CMS
- Writing PHP/MySQL code from scratch (or using a framework)
I know it maybe unrelated, but how good is to use ASP.net instead of these options?
Right. If you are most comfortable with PHP (the scripting language behind WordPress and Drupal), you’ll most likely be more comfortable making the step to Drupal. Pressflow is just a fork of Drupal optimized for particular needs (and there are other forks of it — all of them are really just Drupal and are often the basis for various Drupal distributions).
