Deprecated - Performance and scalability

Is it possible to add user roles within user roles.

example:

Northern Role > Team Role 1 > users
Northern Role > Team Role 2 > users
Northern Role > Team Role 3 > users

Southern Role > Team Role 1 > users
Southern Role > Team Role 2 > users
Southern Role > Team Role 3 > users

Northern Role/Southern Role has permissions to the north/south region, then each team in the northern/southern role has access to their own project and so on.

I run a number of sites that feature lots of files such as images and videos. I have noticed some performance issues with increased traffic loads and also am running into backup issues and stuff like this. I am thinking it would be best to start thinking about abstracting the files directory to its own stand-alone server.

I was wondering if anyone had any experience in handling this in Drupal and could point me in the right direction.

You will feel sluggishness on "administer pages" if your machine has no direct internet access. This problem can be fixed by disabling automatic update while installing the CMS.

Drupal Install >> Configure site (3rd step)

Update notifications: (all the way down)
[ ] Check for updates automatically

Hope this helps others.

Hello folks,

I'm new to Drupal, and I've been looking over its capabilities and the forums over the last few days and have several questions that hopefully you can answer.

My biggest concern with Drupal is its scalability and performance.

Let me describe to you the type of site that we would like to potentially use Drupal for:
- Traffic of approximately 40 million page views per month (within weeks of launch). That's averages about 15 pageviews/second.
- Approximately 1 million users.
- The site will be Digg-like in nature: individual "story pages" each with user comments, voting on comments, ability to upload videos & photos.
- The site will have user profiles that will contain things like stories that the user has "dugg" and his/her friends.

This site's purpose is NOT to duplicate or clone Digg at all, just make use of some of it's cooler features.

Considering the functionality (modules) described above, I've got several questions:
1. How easy is it to install and configure Drupal to work in a webserver farm environment (multiple PHP/Apache/Drupal machines and multiple MySQL database machines)?
2. Can Drupal itself successfully handle (will pages load in about 1 second?) such a heavy load?
3. What kind of hardware specs do you think we would need to have Drupal successfully handle (will pages load in about 1 second?) such traffic?

Hi, currently I'm reading "Pro Drupal Development" and experimenting with Drupal 5.x.Dev.

I stop for a moment after reading this ( Page 4 about Hooks ):
.....Suppose a user logs into your Drupal web site. At the time the user logs in, Drupal fires the user hook. That means that any function named according to the convention module name plus hook name will be called. For example, comment_user() in the comment module, locale_user()
in the locale module, node_user() in the node module, and any other similarly named functions will be called.....

This just doesn't make any sense to me, I must be missing something here. Here's the story...
